The perl and sh scripts at the end of this post seems to work on both CentOS 7 and Ubuntu 18.04 LTS to list drivers missing from the normal CentOS 8 kernels. (The latter is much slower.) Please let me know if you encounter problems with it.

Apparently CentOS 8's default kernel is missing key drivers on every single machine I use, notably the storage and ethernet drivers. So only the most dispensable pieces /s. Thanks a lot Red Hat!

Here is another version which uses /bin/sh instead of perl. It is much slower but may be able to run in busybox or other similar limited environment, so long as /tmp is present and lscpi is also present.

edit: minor change in perl script, added sh script.
