Hi
About Enable-WSManCredSSP, we could refer to this Microsoft Documentation article:
Enable-WSManCredSSP
https://learn.microsoft.com/en-us/powershell/module/microsoft.wsman.management/enable-wsmancredssp?view=powershell-7.1
In general , enabling this for one particular DC will not be replicated to another.
One we need to notice is that this parctice increases the security risk of the remote operation.
Hope the above information could bring you some help.
Best Regards
