How do I hide unavailable variant on my product page?
I’m using Taste theme 3.0.1
For example this Magsafe variant is available for iPhone 14 Pro Max

This will be a problem as my product is customizable.

Do note that I have used an app to fix this problem (in case you go to my website and it has been fixed), but I’m just using it for a while until I can fix this problem, I’m still looking for the method to solve this manually without an app.
