Include CAs for backup

Hi,

I need to include CA certificates for (the) pgBackRest (pods) to trust in-house certificates. How is this achieved?

Anyone? In the pgBackRest documentation, a parameter called repo-host-ca-file can be found (pgBackRest - Configuration Reference). Is there really no such parameter for the operator to include CA certificates for backup with, e.g. base64, secret or something?
