As the keys CFG80211_REQUIRE_SIGNED_REGDB are built into the kernel image, they would be included in the kernel image signature.
As I previously asked https://lkml.org/lkml/2017/11/15/679, how are the keys located in the CFG80211_EXTRA_REGDB_KEYDIR keyring trusted? The keyring does not validate the certificate signatures, before loading the keys on the firmware keyring. It explicitly bypasses the certificate signature validation.
