Custom product page "add to cart" button

I need help with a code for… 3 of my product pages did not need the upload image button. My pages were dynamic, so if I added one button to a product page, all my pages have the same button. I created individual pages for those 3 products but can’t add them to cart. Add to cart button goes to an empty cart page. Customers need to be able to purchase those 3 items and not be confused by having an upload button present. Any help will be appreciated.

Does anyone have any ideas?

I have tried 2 ideas that customer service have suggested, but none have worked correctly
