Hi,
is it possible to downgrade the firmware to an older version as 2022.100.22.0.0?

Thanks
Stephan

Nope. Apple never allowed firmware downgrades and finally closed any workarounds around Thunderstrike time (2015ish). Even if it was possible, would be a futile exercise since the firmware would be automatically upgraded again.
