Since August 2018, I've had a notification to "Migrate to McAfee Endpoint Security Today" in ePO. Other notifications like software updates available either clear themselves, or have a "clear" link/button (I don't recall which). This notification doesn't seem to have any options to dismiss.
The Support Notifications page is a continuously updated news feed that displays notifications received in the last 30 days. Check if you have applied any Tag to that particular update under Support Center-->support notifications. Worth to check. Also see if you have "Endpoint Upgrade Assistance" extension checked in. If you have completely migrated to ENS, if you no longer required this extension, try to remove and check if that helps.
