On my Samsung S10e device I often get these notifications:
Device care - Activate Anti-malware service
and
Battery fully charged
When I try to turn one of them off, I am told:
These notifications can't be turned off
Which raises the question: On my rooted device, how can I turn them off?

Keep in mind that this will disable all Device care notifications. If you went with the second method, you may want to try disabling one at a time to remove the notification you want without necessarily removing all of them.
