x264 does
not have a "maximum bitrate" option (other than the VBV options). And the options available in the GUI are, of course, a strict sub-set of the options that x264 offers.
Note: You can
not have something like a "maximum bitrate" without a properly defined
buffering model. And that's exactly what VBV does. So you actually
want VBV here
