I basically created an extra field with the service name: NO_ADD_CART, and the field name: "No Add To Cart Button", for every product.

This is the code that I placed in the template common_files/customer/buttons/add_to_cart.tpl which is making the add to cart button dissappear for every product on the site.

{if $extra_fields.field eq "NO_ADD_CART" and $extra_fields.field_value ne "no"}
{include file="customer/buttons/button.tpl" button_title=$lng.lbl_add_to_cart additional_button_class=$additional_button_class|c at:' add-to-cart-button'}
{/if}
