How can I block scriptTag js from running on my alternate product template?

My app adds a custom alternate product template to build bundles. When the customers select the products, I will send a cart add POST request with fetch. However, there are many apps using ScriptTag to detect the product page.

Some of them are blocking my add to cart action for some reasons I don’t know (Can’t read their minified js). I think they assume all product pages are standard.
