How to correctly form meta tags in categories?

Question

1C-Bitrix

There is a catalog of goods with categories. Actually, infoblock.
In theory, to customize the meta tags of a category and products in it, you need to change the seo template of a specific category and its elements.
The problem is that if you change the seo of the category, then the meta tags in the products are displayed, as in the category. How can I override product tags?
