Does it make sense to perform Docking on a complex?

I am trying to design an orthogonal ligand/receptor system. I've inherited the script below as a starting point but I'm wondering what exactly the Docking mover would be doing. My PDB structure is a ligand that is already bound to the binding domains on the receptor. Does it still make sense to perform a docking step in this scenario?

My script:

<ROSETTASCRIPTS>
 
 <TASKOPERATIONS> You can control which parts you want to change from here
     
    ProteinInterfaceDesign name="pido" repack_chain1="1" repack_chain2="1" design_chain1="1" design_chain2="0" interface_distance_cutoff="10"/> task operation that designates which residues are designable and repackable at the interface
