Welcome to M1 !
Apple seal now everything. All the processes with Intel are down.
Check FAQ @Apple to see how it works.
Worse and worse everyday

Yeah, they've added DFU mode which apparently is the only way to downgrade, but then you need another mac which I don't have atm. And no internet recovery for M1 macs...

How to Boot an M1 Mac Into Recovery Mode (Compared to an Intel Mac)

Macs can operate in macOS Recovery Mode, which allows you to run emergency maintenance on your desktop or laptop. It’s a special mode that loads native recovery tools that help you out when you are in a jam.

Yes, that's what I thought would happen but the only option I got there was to reload the beta. I then made a BS USB-stick and chose that in boot options instead of recovery and got told that version of MacOS was to old, I also tried that from recovery as it showed up there too but got the same.. too old.

I'll just roll with it until Monterey final at this point

Maybe it is a bug, and Apple should be notified about it because it does not seem right even for Apple to not allow you to go back to the OS the device shipped with.

It is definitely not.
