How to hide "category 1" if the user is in "category 2"?

Question

WordPress

Good afternoon!

Please tell me the plugin to implement the solution:

There are 2 product categories on the site: Category 1 and Category 2 (with subcategories by product type).
If the buyer selects the "Category 1" category, then the "Category 2" category and, accordingly, all its subcategories are not shown.

Thank you!
