Edit: updated per research.

Wouldn't it be, for his example of changing the port:

    Set-WebBinding -Name 'RadWebServer' -IPAddress "*" -Port 443 -PropertyName Port -Value 4430

I don't have a huge amount of PowerShell experience so maybe that's incorrect or has extra bits.

Yes it would be as the OP's question was about changing the binding. My bad.
