Here's my code:

<?php
namespace DemoMymoduleSetup;

use MagentoEavSetupEavSetup; 
use MagentoEavSetupEavSetupFactory;
use MagentoFrameworkSetupInstallDataInterface;
use MagentoFrameworkSetupModuleContextInterface;
use MagentoFrameworkSetupModuleDataSetupInterface;
use MagentoCatalogSetupCategorySetupFactory;
use MagentoEavModelEntityAttributeSetFactory as AttributeSetFactory;


class InstallData implements InstallDataInterface

 private $eavSetupFactory;
 private $attributeSetFactory;
 private $attributeSet;
 private $categorySetupFactory;

 public function __construct(EavSetupFactory $eavSetupFactory, AttributeSetFactory $attributeSetFactory, CategorySetupFactory $categorySetupFactory )
 
 $this->eavSetupFactory = $eavSetupFactory; 
 $this->attributeSetFactory = $attributeSetFactory; 
 $this->categorySetupFactory = $categorySetupFactory; 
 

 public function install(ModuleDataSetupInterface $setup, ModuleContextInterface $context)
 
 $setup->startSetup();

 // CREATE ATTRIBUTE SET 
 $categorySetup = $this->categorySetupFactory->create(['setup' => $setup]);

 $attributeSet = $this->attributeSetFactory->create();
 $entityTypeId = $categorySetup->getEntityTypeId(MagentoCatalogModelProduct::ENTITY);
 $attributeSetId = $categorySetup->getDefaultAttributeSetId($entityTypeId);
 $data = [
 'attribute_set_name' => 'NewAttributeSet', 
 'entity_type_id' => $entityTypeId,
 'sort_order' => 200,
 ];
 $attributeSet->setData($data);
 $attributeSet->validate();
 $attributeSet->save();
 $attributeSet->initFromSkeleton($attributeSetId);
 $attributeSet->save();

 // CREATE PRODUCT ATTRIBUTE
 $eavSetup = $this->eavSetupFactory->create(['setup' => $setup]);

 $eavSetup->addAttribute(
 MagentoCatalogModelProduct::ENTITY,
 'text_new',
 [
 'type' => 'varchar',
 'label' => 'New Text',
 'backend' => '',
 'input' => 'text',
 'wysiwyg_enabled' => false,
 'source' => '',
 'required' => false,
 'sort_order' => 5,
 'global' => MagentoCatalogModelResourceModelEavAttribute::SCOPE_STORE,
 'used_in_product_listing' => true,
 'visible_on_front' => true,
 'attribute_set_id' => 'NewAttributeSet',
 ]
 ); 

 $setup->endSetup();
 

 ?>

All working fine but the attribute is assigning to all attribute set and I want on only one attribute set which I have created: NewAttributeSet

Try This One, Check the New Code Added.

<?php
 namespace DemoMymoduleSetup;

 use MagentoEavSetupEavSetup; 
 use MagentoEavSetupEavSetupFactory;
 use MagentoFrameworkSetupInstallDataInterface;
 use MagentoFrameworkSetupModuleContextInterface;
 use MagentoFrameworkSetupModuleDataSetupInterface;
 use MagentoCatalogSetupCategorySetupFactory;
 use MagentoEavModelEntityAttributeSetFactory as AttributeSetFactory;


 class InstallData implements InstallDataInterface
 
 private $eavSetupFactory;
 private $attributeSetFactory;
 private $attributeSet;
 private $categorySetupFactory;

 public function __construct(EavSetupFactory $eavSetupFactory, AttributeSetFactory $attributeSetFactory, CategorySetupFactory $categorySetupFactory )
 
 $this->eavSetupFactory = $eavSetupFactory; 
 $this->attributeSetFactory = $attributeSetFactory; 
 $this->categorySetupFactory = $categorySetupFactory; 
 

 public function install(ModuleDataSetupInterface $setup, ModuleContextInterface $context)
 
 $setup->startSetup();

 // CREATE ATTRIBUTE SET 
 $categorySetup = $this->categorySetupFactory->create(['setup' => $setup]);

 $attributeSet = $this->attributeSetFactory->create();
 $entityTypeId = $categorySetup->getEntityTypeId(MagentoCatalogModelProduct::ENTITY);
 $attributeSetId = $categorySetup->getDefaultAttributeSetId($entityTypeId);
 $data = [
 'attribute_set_name' => 'NewAttributeSet', 
 'entity_type_id' => $entityTypeId,
 'sort_order' => 200,
 ];
 $attributeSet->setData($data);
 $attributeSet->validate();
 $attributeSet->save();
 $attributeSet->initFromSkeleton($attributeSetId);
 $attributeSet->save();

 /*************** New Code Start ***************/
 $attribute_group = 'New Attribute Group Job'; 
 $this->eavSetupFactory->addAttributeGroup(MagentoCatalogModelProduct::ENTITY, $attributeSetId, $attribute_group);
 /*************** New Code End ***************/

 // CREATE PRODUCT ATTRIBUTE
 $eavSetup = $this->eavSetupFactory->create(['setup' => $setup]);

 $eavSetup->addAttribute(
 MagentoCatalogModelProduct::ENTITY,
 'text_new',
 [
 'type' => 'varchar',
 'label' => 'New Text',
 'backend' => '',
 'input' => 'text',
 'wysiwyg_enabled' => false,
 'source' => '',
 'required' => false,
 'sort_order' => 5,
 'global' => MagentoCatalogModelResourceModelEavAttribute::SCOPE_STORE,
 'used_in_product_listing' => true,
 'visible_on_front' => true,
 'attribute_set_id' => 'NewAttributeSet',
 ]
 ); 

 /*************** New Code Start ***************/
 $this->eavSetupFactory->addAttributeToSet(MagentoCatalogModelProduct::ENTITY,$attributeSetId,$attribute_group,'text_new',null);
 /*************** New Code End ***************/

 $setup->endSetup();
 

 

 ?>

Simply change the below line

'attribute_set_id' => 'NewAttributeSet',

to

'attribute_set' => 'AttributeSetName',

Now your attribute get assigned to above mentioned attribute name.

To prevent Magento 2 from adding your attribute to all attribute sets (as of Magento 2.3.1):

• You must set 'user_defined' => true, in the array passed to addAttribute().


• You must not define a group key in the array, otherwise Magento will add your attribute, in the specified group, to all attribute sets.


• You don't need to define an attribute_set_id key (nor attribute_set). It doesn't do anything.


• You don't need to specify a sort_order key. It is only used when Magento adds the attribute to all attribute sets.


• You need to call addAttributeToGroup() after addAttribute() to add it to the attribute set you want.

The code would look like this:

$eavSetup->addAttribute(
 MagentoCatalogModelProduct::ENTITY,
 'text_new',
 [
 'user_defined' => true,
 'type' => 'varchar',
 'label' => 'New Text',
 'input' => 'text',
 'required' => false,
 'global' => MagentoEavModelEntityAttributeScopedAttributeInterface::SCOPE_STORE,
 'used_in_product_listing' => true,
 'visible_on_front' => true,
 ]
);

$eavSetup->addAttributeToGroup(
 MagentoCatalogModelProduct::ENTITY,
 'NewAttributeSet',
 'General', // group
 'text_new',
 5 // sort order
);
