App Recommendation: Hide a specific product from collection page, but don't hide the product itself

Hello!

I’m looking to hide a specific product from a collection page. I have my store set up so 2 products essentially act as variants using an app (I have to set it up like this because of POD provider limitations). So, I would like to only display the original product in the collection and not the second product (that acts like a fake variant).

They have to be in the same collection to preserve the collection/category breadcrumb/taxonomy.

How can I hide these secondary products from a specific collection? Any apps for that?

I needed to do a similar customization and installed this app:
https://apps.shopify.com/scala-hide-sold-variants

Although they don’t offer this feature out of the box, I sent them a message, and they adjusted the app to achieve this on the same day.
