To remove a boot entry type      efibootmgr -b 0002 -B   and replace the 0002 with the entry id's that you intended to remove

Remove from Windows CMD not powershell::

bcdedit /enum firmware

Then it shows the entry list, and we must delete with the identifier id like so:

bcdedit /delete {f94c2646-0636-11ec-a9d3-c67bffde298a}
