Single Product "Add To Cart" Button Delete? HTML CODE.

You can remove the add to cart button from the single product page by adding this to your theme functions.php file

remove_action( 'woocommerce_single_product_summary', 'woocommerce_template_single_add_to_cart', 30 );

But that will remove it on every product.

If you want to be selective then you need a function and a way of letting that function know that the Escrow button is there.

If the Escrow button is being added using a short code in the content then something like this https://wordpress.stackexchange.com/questions/40733/check-for-shortcode-in-post-pages-and-widgets-and-template-files will let you detect the short code and you can then use remove_action above
