This request is still on the backlog.
As the last status states, we have been testing for several months. Although many people have asked for this feature, we received a similar amount of feedback from other users that they prefer the Teams notifications and don’t want them changed. We are currently testing a feature for users to choose between Teams notifications & Windows notifications.
We will update you as work progresses.

Please can Teams notifications just use the standard system notifications in Windows 10 so that integrate into Action Center and behave like other notifications. It's strange that a modern Microsoft app doesn't do this from day 1.
