On that platform, AVC with NBAR2 (and possibly performance routing) would be the recommended option. It'd be difficult to outright block the traffic but your could throttle it down to discourage the behavior.
You could also enforce the behavior through combination of a written policy and follow up with any offenders that you identify via something like Netflow reporting.
