shopify code

I am looking for a Shopify developer who can simply hide the "Add to Cart" button on certain products that trigger a "personalize design" button via Printful integration. This "personalize design" button is triggered by Javascript code via Printful. I need to hide the "add to cart" to force visitors to always use the "personalize design" button on certain products only, not the entire store. (see example below).

*Access to the online store is not granted. You will need to send the code to be modified along with instructions on how to do it.
