I come across this need often also, as many MS4W users leverage GDAL 
through netCDF, HDF5, HDF4, but I'm not aware of a GDAL commandline 
option to 'skip' raster drivers (OGR has "OGR_SKIP").  I could be wrong 
though.  I have seen other users request this 
(https://trac.osgeo.org/gdal/ticket/5917) which seems to say that there 
is a way through the GDAL API, but, I'm just not sure about the commandline.
