Recent Ubuntu dist (server) for 4c+ - low power consumption

Hi all,

New Rock Pi user with a couple of 4c+ devices.

Is it possible to get Ubuntu server up and running with low power consumption? Some posts suggests that 2W idle should be possible, I end up with 4W with Armbian.

The Radxa ubuntu image could not be burnt successfully on SD card from either Rufus(Windows) or UsbImager(Linux).
