So "secure-boot-enrolled-keys" also has SB turned on.

Yes. So "secure-boot" specifies "firmware binary supports secure-boot"
and "enrolled-keys" specifies "firmware nvram template has keys enrolled
(and SB enabled).
Other question: Do we want allow to specify which certs/keys are
enrolled? Which would probably mean to drop "enrolled-keys" from
features and make it an optional string instead, then specify
"'enrolled-keys' : 'Microsoft'" in the json file.
cheers,
Gerd
