this should have an entry RESTRAINTS and that is all you need to subtract.
If I remember correctly, dvdl_norest only changes the reported output, not
your simulation results. If you want to test my recollection, run a simple
simulation twice with dvdl_norest on and off and see if the difference in
dvdl matches the RESTRAINT entry.

Kind Regards,
