Editing Meta Description of Category Not Just Parent Page

I am back with the same problem of editing meta description of Discourse page, but on the next level. We need to change the meta description of a category, not the parent page alone.

Every time, we run an SEO audit of the site, we get an error that the main community page, privacy policy page, ToS page, and category page have duplicated meta descriptions. So I am looking for ways to edit the meta description of the privacy policy page, ToS page on our discourse account. Do you know of a way to do it? I had added comments on the other page with same topic 14 days ago and did not receive a reply. So, I am reaching out again for help.
