Shipping build doesn't recognize "r.DistanceFieldAO 0"

I have build my game as shipping and started a closed beta. Players are complaining since they can’t stop the DistanceFieldAO effect and it kills the framerate on slower hardware.

On a development build this console command works but:

Is there a way to stop the console from appearing ?
Will it run without the engine ?
I am using 4.7.3

Please consider this for Hot fix 4.7.4

I have a post on the forum here:
I can provide steam key for testing.
