Proportioning Valve

I’ve been trying to figure out if my 2010 328i x-drive had a proportioning valve for the brakes in its OEM stock form. If it does indeed have one then is it electronically controlled by the computer? Mechanically controlled based on which wheel needs optimal braking force? Another follow up question would be could you change the front-back pressure. If it does have a proportioning valve what is the pressure rating for the front/rear? 50/50, 70/30, 90/10? I guess my goal would be a lesser braking distance without changing much with the physical hardware.

Thanks,
Tyler
