Certainly; see https://salilab.org/modeller/10.1/manual/node58.html and 
https://salilab.org/modeller/10.1/manual/node57.html

By default Modeller writes a trace file (e.g. 1fdx.D00000001) with 
energy values and other optimization statistics. If you also want 
coordinates or other information, you can set write_intermediates=True 
or override get_optimize_actions() to add additional optimizer actions 
such as WriteStructure (to write PDB files) or CHARMMTrajectory (to 
write a DCD trajectory).
