dpkg-source is invoked via:

gbp buildpackage 
  -> git-pbuilder
    -> pdebuild
      -> dpkg-buildpackage
        -> dpkg-source

It just passes on all options you give from gbp buildpackge to
dpkg-buildpackage. See the man page of dpkg-buildpackage, I don't think
you can pass arbitrary option from dpkg-buildpackage to dpkg-source
there.
