ZFS Rescue Boot on HBA not working

I am running a HP P420 in HBA/IT Mode.
Even I cannot boot from it, I am also not able to use the Rescue Boot from the Installation Media.
The Disks aren´t even Blinking on boot.

Is there a way to Rescue Boot from a HBA?

Out of my experience with a P420i I can say that it is not possible to boot from it if in HBA mode as the disks are just not "visible" during that stage during booting. No idea what HP has done there in the firmware.

Possible ways to proceed:
  1. install Proxmox on other disks, connected to the SATA controller for example
  2. get a real HBA as apparently the HBA mode in the P420 is kinda broken
