ISE Trusted certs showing expired

[NetworkMonkey101]

I have three expired trusted certs, are these ok to delete?

             I would presume it is safe to delete the others also ,

I think the Verisign Class 3 cert is used for Smart Call Home. I cannot see this option within ISE 3.3. Where can I see if this is in use?

   @NetworkMonkey101   Looks like it when looking at https://www.cisco.com/c/en/us/support/docs/cloud-systems-management/smart-call-home/215210-troubleshooting-certficate-exipry-alert.html
