Replace “Add to cart” with a contact link

I tried to do what the following link says, but I can’t do it.

https://help.shopify.com/en/manual/online-store/themes/os/customize/replace-add-to-cart

At the beginning it says I can contact someone and ask for help.

“Note
If you use a free theme from Shopify, then you might be able to contact Shopify Support for help with this tutorial. It requires 15 minutes of design time. To learn more, refer to Support for themes.”

I want to remove the add to cart and buy now option on each product as well as on the main menu.

Ideally, I would like to have a button below the product description to redirect them to the contact form to place an order.

I would like to deactivate the option to buy, the page is more used as a catalogue, for the moment we have to remove the direct purchases.

Many thanks
