Trying to convert Chromebox into “regular” pc

I watched Danimationstips on how to do so, everything went well until I tried running the firmware utility script, which then this popped up

I checked my model name which is FIEVEL D25-B4D-A5A-B6I, but i dont see that name on the chart in the video. Is it still possible to continue converting it into a pc? What should I do.

Arm is currently unsupported by the Chrultrabook dev team.

PostmarketOSopen has support for a few ARM Chromebooks.
