Display produkt quantity without quantity in cart

[GeorgeP]

Hello everyone,
Please help. I can't find a solution. I want to display the real quantity in the product detail and in the product list. The problem is that the number in the cart is deducted.
Example:
I have 10 pcs in stock
I will add 4 pcs to the cart
It will show 4 pcs in the basket and 6 pcs in stock.
I would like to see 10 pcs in stock until the customer confirms the goods. At the same time, I want to make sure that the customer cannot buy more pcs than is in stock.

I need this:
$product.quantity (in file: product-details.tpl) = 'quantity' from TABLE 'ps_stock_available'.

I wanted to edit it in the template code, but I don't know where or how. I tried something but it didn't help me.

Is it possible to solve it? I have Prestashop 1.7.6.5
In version 1.6 it worked.

Sorry for my english 😕

Thank you wery much for my help.
