hide quantity buttons when product price is 0

Hi, I am the developer of the licence bought from info@mariacandidagentile.com.

We installed your plugin in our site https://www.mariacandidagentile.com and we are using a gift plugin to manage the gifts.

The “problem” is that: when we put as a gift a normal product, the cart AIO plugin shows the change quantity buttons so the user can increase the quantity and issue the order ( see image https://ibb.co/6FYHszd ) . So, the question is, can we hide the quantities buttons for products that has a price = 0? do you have a snippet or so? thanks
