According to the log, the dGPU has a single VGA port.  I doubt it's muxed, just
about all AMD PX laptops have been muxless for a while now.  It's probably a
VGA port on a docking station.  As Lukas mentioned, if you want to use the
dGPU, you can only use it for offscreen rendering.  See this page for how to
utilize that functionality:
