Is someone of you able to boot a recovery with the ultimate version?

I'm trying to boot TWRP but I always get the error

Sending 'boot.img' (98304 KB)                      OKAY [  0.343s]
Booting                                            FAILED (remote: 'Unrecognized command boot')
fastboot: error: Command failed

Is there anything I can do about it?

Things I've tried:

* 3 different PCs

* 4 different USB cables

* all USB Ports

* different ADB/Fastboot versions

I searched all over the place but every solution so far fails - however I was not able to find an issue related to the Asus ROG Ultimate so maybe there is something special here?
