apt-cache search linux-image and installing the latest from there.

Our latest official Kernel version is the same 4.9.312 as you found to support the GPU & VPU HW acceleration.

If you don't need the HW VPU (4K video playback) acceleration, freshly flash @tobetter's Ubuntu 22.04 image which supports the upstream Kernel 5.18 since Kernel updating path from 4.9 to 5.1x is not available.

How can I upgrade to 22.04 from my 20.04 build?

You can do sudo do-release-upgrade -d, but you may need to manually re-enable hardkernel's repos after the upgrade.

Thanks, sorry for being such a noob!. Where are those repos located at, so i can copy and paste?

After the upgrade you'll need to update the files in /etc/apt/sources.list.d/*. Uncomment the lines containing "jammy" and run sudo apt-get update; sudo apt-get dist-upgrade to finish.
