Powershell cmdlet to install a CA certificate on c7000 Onboard Administrator

[Sam2018]

Thank you for your help. We have a very strict security policy so I cannot use FTP or TFTP, not even on my workstation. I have checked the documentation before posting here but it only mentioned the "-url" option using a protocal (example: FTP). I just wanted to check if there is a way for this to work which would save me replacing the certificate manually on all c7000s.
