Fedora has it.

CS-10 has it (-> RHEL-10):
redhat/configs/common/generic/CONFIG_KUNIT:CONFIG_KUNIT=m

https://gitlab.com/redhat/centos-stream/src/kernel/centos-stream-10/-/blob/main/redhat/configs/common/generic/CONFIG_KUNIT?ref_type=heads

CS-9 has it (-> RHEL-9):
redhat/configs/common/generic/CONFIG_KUNIT:CONFIG_KUNIT=m

https://gitlab.com/redhat/centos-stream/src/kernel/centos-stream-9/-/blob/main/redhat/configs/common/generic/CONFIG_KUNIT?ref_type=heads

So I think from the RH side everything is properly set?

Let me CC Nico, he did some KUNIT work in the past.
