how to genarete and enroll custom secure boot keys – HP Support Community

I wish to run my “HP Elitebook 850 G5”  dual booting with “Windows 11” and “Manjaro Linux” keeping TPM enable. But Manjaro linux doesn’t support secure boot natively. So, I genareted “mechine owner keys” as “PK.auth” , “db.auth” , “KEK.auth” from Manjaro Linux . But it seems my laptop doesn’t support ” .auth” format keys, it needs ” .bin” format keys. 
So, how can I create ” .bin” format keys and enroll it in bios.
