I'm using Ubuntu 20.04 on it at the moment. In order to boot custom
images you'll need at least to install a custom recovery, which will
allow to flash boot.img on eMMC storage.

Ideally, you'll need to install an unlocked bootloader that will enable
Android's fastboot, and thus, allow to easily boot kernel zImage without
messing with flashing boot images.

Could you please tell what is the current state of yours device: does it
have a stock Android installed? is it rooted? is custom recovery installed?

My device was unlocked about 8+ years ago, so I'm not sure what's the
best way to do it nowadays. The XDA forums [1] could be a good starting
point, I may give you some advises once you'll tell what's the current
status of yours device.
