Did you check the tutorial?
I think this is what you are looking for (at the end)
"Because either automodel or loopmodel will build a comparative model using your input PDB as a template, potentially all of the atoms in your final model could move. If you really don't want the non-missing residues to move, you can override the select_atoms method to select only the missing residues with a script similar to that below"
I hope this helps
