how to have 2 comments_template() in one post

I have an issue in my new theme.
my website is about Education for teachers and students. every post belongs to one teacher that students can talk to her/him via comments.
now, i want to add a special thing to any post. i want to have two comments_template() in one post with pills (bootstrap). in one, student can just ask their questions but in another, they can do review and rating.
in fact i need to use different comments_template file for every one.
