Hi, did a quick search, found this plugin, you might want to try it.

Hello keshabee, currently only the administrator can hide users, users cannot hide themselves.
Screenshot has been uploaded and the plugin now supports higher wordpress/php versions.
Many thanks for reaching out. If you have any issue or feature request, do not hesitate to share.
Cheers!
