Had trouble installing macOS sonoma and was told to try disabling FindMy, in doing so I accidentally erased my device from it instead and now im stuck at the recovery screen and MacintoshHD is missing. The only thing that shows up in Disk Utility is APPLE SSD AP0256Q, im unable to erase or partition the ssd, and unable to reinstall macOS big sur.
MacBook Air 13″
FindMy has been disabled for the Mac, I’m still unable to erase the disk.
What error message is there if you try to erase in Recovery mode? Does Internet Recovery behave the same?
If all else fails, you might have to revive or restore the Mac's firmware using another Mac.

I cant get past the recovery screen since i need to reinstall macOS, and I've tried mostly everything. The only issue now is having to revive it since I don't have another mac.
Hmm. Maybe the Silicon Mac has lost the "Owner" and its firmware must be restored.

If you did not yet successfully disable Find My Mac for that Mac, use a browser to connect to iCloud and try to disable it there.
Then you can erase that Mac's disk as APFS (case insensitive) and install macOS, then restore from the backup.
