See http://salilab.org/modeller/FAQ.html#3
model.patch_ss_templates() adds disulfide bonds to your model if you
have a Cys-Cys pair aligned with a disulfide bond (determined by
inter-residue distance) in the template. This is done automatically for
you by the automodel class anyway.
model.patch_ss() adds disulfide bonds for every Cys-Cys pair in your
model, if they are sufficiently close. But this is probably not suitable
in your case.
model.patch() is used to manually add disulfide bonds, is probably what
you want, and is described in the example at the link provided above.
