removing root access notification (#) in status bar

[nbi]

Has anyone figured out how to do this? I know how to remove notifications in general, just not this specific one (#). Thanks.

I could imagine that a root-app could somehow prevent that the notification is removed. Did you try to long-touch the notification to see if it's coming from the root-app?
What root-app is responsible for the notification, SuperSU or another app?
