How do I hide old wordpress posts from user?

There are 12000 posts submitted on my WordPress website and I want to hide a few of those posts from the user (100 posts). I neither want to delete posts nor want to draft those posts. I used Archived Post Status plugin. After installing the plugin I set the post as Archive from the backend. But the post was still showing with title Archived – Hello Word (Post Title).

Is there any want to hide those posts from users?
