Macbooks with M-series CPUs can be configured to boot arbitrary payloads: https://support.apple.com/en-gb/guide/security/sec7d92dc49f/1/web/1 (see "Permissive Security policy")
This is the mechanism used to boot alternate OSes like Asahi Linux.
The new Macbook Neo uses an A18 Pro CPU. Can it be configured to support booting arbitrary user-provided (non-macOS) payloads?

@MartinSundhaug The third party oses supported by the m-series are just tolerated whenever they break stuff with asahi they don't care so it'd be a surprise if they put serious engineering effort to get it working for the a-series for a minority of their customers.
@overflow IIUC the A18 is a part of the M4 family so I don't think it'd take that much if they want to
@overflow They put a lot of engineering effort into making it work on all other apple-silicon mac products released to date.
If they don't support it on the Neo it won't be because they can't be bothered, but because they consider it a new market segment.
@retr0id + even if you end up running Asahi Linux on a MacBook ... Apple still (probably) made money on selling you the hardware
Good, should always on a PC be able to press a key or similar right at the start of boot to enter the bios setup and configure it, including arbitrary drive to boot from, that you can put your own information on.
