Apologies for the inconvenience. Unfortunately, it is not possible to completely disable the cart in EasyStore. However, you can hide the “Buy” button from the product listings and product detail pages. Since these pages are created using SP Page Builder, you can remove the “Buy” button directly by editing the page: EasyStore integration with SP Page Builder.
Additionally, the cart button is often displayed through a module in most templates. You can disable this module to remove the cart button from the frontend. While it is not possible to turn off the cart functionality entirely, these steps will allow your site to function as a menu with pricing only.
We appreciate your understanding.
