Try with this code:

$item = $this->cart->getQuote()->getItemById($itemId);
if($item)
 $qty = $item->getQty(); 
 if($qty > 2) 
 $newqty = ($qty - 1);
 $item->setQty($newqty);
 $item->save();
 

$this->cart->getQuote()->save();

Also, you have to Update Mini Cart using sections.xml When you hitting this above code.
