UEFI SecureBoot has an indicator variable called "SecureBoot" of EfiGlobalVariable GUID. It has a value of 0x01 (UINT8) iff SecureBoot is enabled.

You should also check "SetupMode" variable of the same GUID to have a value of 0x00 (UINT8), this indicates that PK, KEK and db are indeed ready and can't be replaced without authentication.
