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
Building Image
apt install git
git clone --depth=1 --branch=main https://github.com/armbian/build
cd build
./compile.sh
