commit 278311e417be ("kexec, KEYS: Make use of platform keyring for
signature verify") adds platform keyring support on x86 kexec but not
arm64.
The code in bzImage64_verify_sig makes use of system keyrings including
.buitin_trusted_keys, .secondary_trusted_keys and .platform keyring to
verify signed kernel image as PE file. Make it generic so both x86_64
and arm64 can use it.
^uses the keys on the .builtin_trusted_keys, .machine, if configured
and enabled, .secondary_trusted_keys, also if configured, and .platform
keyrings to verify the signed kernel image as PE file.

I've applied the two suggestions, thanks!
