Which Filter To Use To Remove comment-metadata

Hi Team,

I need help with the GP theme, can you please tell me:

1. Which Filter To Use To Remove “comment-metadata” and that “at” as well?

2. How to add author profile image along with the author-name, updated date and categories on the blog, archive, and single post pages (Screenshot (I want): https://imgur.com/a/iF73rWb)

Thanks, I look forward to your reply.
