There are one or two other threads about general linux support on this forum. I updated my Arch machine to kernel 5.7 to get it working, as a patch was accepted into the kernel source at the end of the 5.6 branch.
Unfortunately, chromeos has only gotten as far as the 5.4 kernel so far, although with the amount of improvements in the recent kernel 5.8 release, it's possible that this may become the next baseline for chromeos.
Look at the posts at the end of this thread for info (it's not all from 2013:))
