MAAS on Armbian?

Does MAAS support devices running Ubuntu-flavored Armbian?

Given the current incompatibility with Raspberry Pi 4s, I looked into building SBC clusters out of alternative hardware. The SOPINE A64 compute modules [1] mounted on a Clusterboard [2] [3] look perfect for this.

Now, Armbian Focal does support these devices and I’m curious if there’s anything about an official Ubuntu Server image which is missing to bless these devices.
