With a new version of Edge Chromium there is of course new setting we can do = new ADMX/AMDL files. It is important for admin to keep up so even if we allow auto-update of Edge Chromium there is still work that needs to be done for every new release.
This is the new Group policy settings I found that is new for Edge Chromium 80 and 81.

This one is really nice,”Hide the First-run experience and splash screen” no more first-run experience and splash screen!
“Configure Microsoft Defender SmartScreen to block potentially unwanted apps” is a great addition.
Lesson learned, admin need to keep track and update the .ADMX/ADML for every new release and keep an eye on deprecated settings as well.
