If you are confident of this orientation, put the two chains in a single
PDB file, as is done in the example in the manual:
https://salilab.org/modeller/9.25/manual/node29.html
Modeller extracts internal distance restraints from each template
separately, so if your two chains are two separate templates, there will
be no inter-chain restraints.
