It uses all aligned residues in all templates and weights them using a function of local sequence similarity, distance from a gap, etc. See the 1993 paper for a full description.

You have several options. You could override the functions that generate the restraints (see the build_charmm_restraints() and distance_restraints() methods in modlib/modeller/automodel/automodel.py), you could add and/or remove restraints after this is done, or you could manually edit the .rsr file.
