@Jazzoo Sure, see here @FoUStep Yes, should work for your Monterey too, they are similar hardware

@Jake Lo and @Jazzoo, it worked as advertised. Even with FileVault on and an inplace upgrade from Catalina to Monterey which I figured I should just try because there was nothing to lose. Even all kext work properly for me (including my own DW1802A). Thank you for the EFI! Can recommend this to everyone.
