Showing different Content on each eye 5.6 IOS native cardboard

Hi im using Unity 5.6 with native Cardboard VR enabled on IOS
and i want to display stereo Images so different content on each eye .
before i used google cardboard plugin with the 2 camera setup so i could easily switch layers
but
how would i do that with the native integration of cardboard?

i logged already all objects in the scene an just found the one camera … some got any tips?

We created a shader for this, since it performs better:
