Change Target Eye rendering within script

Hello,

I've started developing for GearVR in Unity. I found the camera settings for VR to be very helpful and was able to generate an environment with ease. I have the following setting in Unity:

 Target Eye: Both

I would like to change this setting from within a script while the app is running. I am not able to find a way to change it. When debugging and checking targetDisplay, I find that it outputs 0. which doesn't to give me enough information regarding changing the what the camera renders and to which eye. Is there is way of changing the above setting (Target Eye) from within a script ?

Thanks
