I have found an effective way of removing stubborn local creases is
to humidify the area locally with a fine-nozzled ultrasonic
humidifier, urging the crease apart as the paper relaxes, and then
immediately weight the area under a piece of warm blotter or
matboard.  A fine teflon burnisher may be helpful in reforming the
paper shape, provided you can avoid changing the gloss of the
paper.  This process generally needs to be repeated several times.

This technique usually causes some overall distortions in the piece
which will then need an overall humidification and flattening.  It
sounds like that may not be possible on this support, so I would
heavily weight every inch of the  except for the part you are
working on; this will minimize the overall distortions.  Even so,
you may be trading a tight localized crease for a gentle overall
undulation.
