Samsung 970 Evo Plus 250GB M.2

I’m trying to get the Rock Pi 4 4GB 1.4 to boot from nvme by flashing the bootloader on SPI. Tutorials state that my nvme should show up as MD0 which it doesn’t (Ubuntu server image). Now I found in the Raxda wiki that the Samsung is working under Linux kernel but not directly in the bootloader. I should have checked that before buying the Evo but I didn’t. Is compatibility still being worked on or should I simply buy a nvme which is listed as known to work? Any known work around to get the Evo playing along?

Regards

Or boot with eMMC/SD until then? With Armbian, the same way as years ago.
