Which jobtype are you submitting with? One way to check is to view the job's "prototype" value in WranglerView or ArtistView.
If you're using the "maya" jobtype, there's not really a command-line available for modification, but if you're using the batchRender "cmdrange" or "pyCmdrange" jobtypes, the submission interfaces have a "command template" where you can add this extra parameter in. Or are you exportinb .RIB files and rendering with one of Pixar's command-line utilities?
