Hello,
Try using ConfigureKeyboardShortcuts policy to disable the shortcuts.
Configure the list of Microsoft Edge commands for which to disable keyboard shortcuts.
See https://go.microsoft.com/fwlink/?linkid=2186950 for a list of possible commands to disable.
If you enable this policy, commands in the 'disabled' list will no longer be activated by keyboard shortcuts.
If you disable this policy, all keyboard shortcuts behave as usual.
Note: Disabling a command will only remove its shortcut mapping. Commands in the 'disabled' list will still function if accessed via browser UI.
