How to Manage Enhanced Notifications
The specifics of how Enhanced Notifications prioritizes your notifications are vague.
There’s no setting in Android 12 to let you manually set how Google’s AI prioritizes your notifications.

Should I Turn Enhanced Notifications Off?

It’s hard to say whether you’ll notice a difference in either case.
An immediate change wasn’t noticeable in our testing.
There is one concrete reason you might want to turn Enhanced Notifications off.
The feature warns it “can access notification contact, including personal information like contact names and messages.”
