MacBook Air M1 2020 is power on when lid open.

The ability to disable this "feature" was removed on all M1 (and I believe M2) MacBook Airs and there is no command that can be used to disable this "feature". The same is true with pressing any key on the keyboard when the M1 MacBook Airs are powered off which makes cleaning the keyboard a pain.

This is apparently a hardwired "feature" now and cannot be changed using any software tweak or magic wand.

I have an M1 MacBook Air and tried everything and it s simply just not possible to disable this "feature".

I believe the correct command is: sudo nvram AutoBoot=%03

This command sets the AutoBoot variable to a different value, effectively disabling the automatic power-on when you open the lid. After running this command, restart your MacBook Air, and it should no longer turn on automatically when you open the lid.

tried that and it still powers on.
