/PBENGSVCSTARTUPTYPE : Specifies the startup mode for the PolyBase engine service: Automatic (default) , Disabled, and Manual.
/PBPORTRANGE : Specifies a port range with at least 6 ports for PolyBase services. Example:
/PBSCALEOUT : Specifies if the SQL Server Database Engine instance will be used as a part of PolyBase Scale-out computational group. Supported values: True, False

Start by locating the SqlSetup DSC Configuration and its existing SQL Server installer option handling.
