I am only an occasional Windows user and have not really used Windows
11, so I don't have a way to test on my end.

I did find:

" Uninstall in Settings

Select Start > Settings > Apps > Apps & features .

Find the app you want to remove, select More > Uninstall.

Note: Some apps can't be uninstalled from the Settings app right now.
For help uninstalling these apps, follow the instructions to uninstall
from Control Panel.

Uninstall from Control Panel

In search on the taskbar, enter Control Panel and select it from
the results.

Select Programs > Programs and Features.

Press and hold (or right-click) on the program you want to remove
and select Uninstall or Uninstall/Change. Then follow the directions on
the screen.
