Nebra miner to run Linux

Hello community,

I have some Nebra miners lying around. As the project is next to death or at least I can’t earn with them. I want to reuse the Hardware. I open up a Nebra miner and Se it is a Rock Pi 4 plus v1.73.
So I want to run linux on it ubuntu or debian.

It does seem to boot some kind of linux off the build in system. Where I can’t exit the screen.
Could I reuse it to boot some kind of distro?

I can use the nvme module or a mini sd card.
Thanks for help
