BigFix Relay's have SSL Cert Vulnerability

Ever since Tenable Vulnerability 121009 - SSL Certificate Validity became active I have been receiving warnings that all of my Relays are using SSL certs which have a duration greater than the now recommended amount.

Am I right in saying that Relay SSL Certs are internal product certs? And not something that we can configure.
Has anyone else experienced this issue and found a solution?

Thanks

Yes, correct, those are internal product certificates, and cannot be configured otherwise.
