@Lelle I usually use the Station M2 edge images from the community builds: https://github.com/armbian/community
I prefer the Ubuntu based images (lunar as of now).
Most importantly, you'd need a proper dtb to point to. I have attached the rk3566-box-demo dtb (and its source dts) that I'm using right now. This dts is the latest from mainline kernel with an additional patch to allow the usb 2.0 port to function.
I assume you know where to place the dtb file and how to update your extlinux.conf file to point to it. If not, then please feel free to ask further questions.
