Hi @Darryl
According to the official document, Set-CsUser cmdlet also applies to Skype for Business online. For more details about this command, you can refer to:
https://learn.microsoft.com/en-us/powershell/module/skype/set-csuser?view=skype-ps
If you want to enable enterprise voice in Teams, you can try to connect to Skype online PowerShell before running Set-CsUser:
Import-Module SkypeOnlineConnector
$sfbSession = New-CsOnlineSession
Import-PSSession $sfbSession
