Disable Gamepad Rumble on PC and Invert X-Axis?

Is there a way to disable rumble support and invert the X-Axis for the gamepad on the PC version? I cannot find them. But I was able to find the invert Y-Axis option.

 

I have found the 360 controller to be better suited to this game than a keyboard and mouse setup but I always play with inverted camera controls and cannot use gamepads with rumble.

 

Also, does anyone know if it is possible to disable the depth of field effects without losing the other shader quality options? I like the lighting effects but dislike the texture blurring of DOF. Especially when it is something I am trying to shoot!

I play the Steam PC version of the game using the Pinnacle Game Profiler, which has the ability to remap Xbox 360 or similar controller buttons and joysticks, including inverting them. Hope this helps.
