[Xiaomi Mi 11 Lite 5G] _11Lite5g:
You can uninstall applications using package-manager (pm) inside adb without root privilege, even if you cannot disable / uninstall them from your phone interface.

Enter in your android shell with:

adb shell

List packages

cmd package list packages

Uninstall the application (remove the "package:" if you used the previous command to list them)

pm uninstall -k --user 0 <package-name>

-k : Keep the data and cache directories around after package removal.

--user 0: The user to disable

Re-install an uninstalled package

cmd package install-existing <package-name>

List all packages you uninstalled. Run it from a bash shell: not in adb shell

diff <(adb shell pm list packages) <(adb shell pm list packages -u) -n | grep ^package:
