Disable Site Stats Module

We use this plugin to control what our end users see on Multisite. It’s overkill for what you are trying to do, but you can delete any items from lines 27-50 that you want to keep, and leave the rest (or just comment them out with // )

This will help you on this query as well: https://wordpress.org/support/topic/disable-feedbackcontact-form-module/
