Hello, I don't believe that it does currently.
Originally, support for HDF5 and NetCDF both used the cpl_userfaultfd mechanism https://github.com/OSGeo/gdal/blob/master/gdal/port/cpl_userfaultfd.cpp). The thing that prevented HDF4 from using that mechanism was that its underlying library did not have the ability to operate on a block of memory (the cpl_userfaultfd provides a user-mode page fault handler that fills pages on demand using the VSI mechanism). It is my recollection that a more direct method was found for HDF5 so that it no longer uses cpl_userfaultfd; perhaps a similarly more direct mechanism exists in HDF4? I do not know whether it does or does not.
