The debian version it's based on appears to be bookworm (which is what we want)

Enable Kernel Updates

There is a menu option to switch kernels here

armbian-config
# Select System -> Defreeze
# Select System -> Other

However, selecting a different kernel here just seemed to delete the kernel image / make the system unbootable
The most recent kernel for supported is 6.1.11

Overclocking

It looks like by default it's doing a bit of overlclocking

over_voltage=2
arm_freq=1800
