Sure, I will be happy to help as much as I can without burning myself ;)

Seems [1] Alma Linux has backported DAMON on their 4.18 kernel. Maybe you can
try their port first?

Also, what is the oldest kernel that you have to use? As newer it is, the
backporting will be easier. When I was in AWS, I backported DAMON of v6.7 on
the v5.10 based Amazon Linux kernel, and the source is available on GitHub. So
if you can use 5.10 based kernel, using that could also be a good option.
