RatOS on Orange Pi Zero 2 or other non RPis?

Hey,
I got an Orange Pi Zero 2 here and want to replace the RPi3A+ because it got no LAN-Port and only one USB-Port. It is possible to get RatOS running on it?
I know that, I can install armbian, Klipper over KIAUH and add the Repo for the Printer Configs and Theme manually.
How is that without RatOS to compile Klipper Firmware for the controller boards?
Thanks!
