No that is not intended use case for  ConfigureWithoutCarrier=. It will
only look during configuring the the link.
 While configuring a link even if that link has no carrier it will go on
set it as configured for example empty bridges.

already configured via gained carrier not via
ConfigureWithoutCarrier even if you set it to true.
