There are no Armbian builds that old, in fact Amlogic TV boxes weren't incorporated into Armbian until later Linux kernels. What you must have been using would most likely have been a fork of Armbian.
What you are asking for isnt possible in the way you are asking. You essentially want Armbian ported to the 5.15 Linux kernels, which is a huge project.
You would be better served but spending a month or so figuring out why current kernels don't work for you and fixing that.
