How to use Secondary Encryption Key When Create Pak File

Is there Secondary Encryption to Pak in UE5?

i want to use Secondary key and Apply it.

But even after a lot of effort, UAT does not apply.
i try command line like this : -encryptionKeyOverrideGuid={keyName}
However, on my understand, this command that {keyName} is used as a replacement for the Default key.

How do i use it?

How can I do double encryption?
