Disabling rear 02 sensors on 2006 Ram 1500 5.7L

[BullnOblue]

I hav ea predator 7137 tuner. I recently installed Kooks long headers on my vehicle. Can I disable to rear 02 sensors with the tuner or do I need a custom tune. If I do how do I go about that? I tried calling the tech line several times and can never get thru.
