Mac Pro 5,1 Monterey Firmware update loop #251

Hi, I'm having troubles to install Monterey with this script (modified to Monterey paths) or this fork on Mac Pro 5,1 with Metal compatible GPU GEFORCE GTX680. I can install Big Sur just fine though. Monterey is stuck in the firmware update loop "A required firmware update could not be installed" forever. I've tried to create a bootable USB with all assets (--downloadassets key) but that didn't help. Anybody have any idea what to do?
