Building AOSP without Driver Binaries

[drainzerrr]

I am building User debug Build For Nexus 5x and Nexus 6p. The issue is that the version i want does not have Driver binaries available. Should i just build without driver binaries.

(Building is very costly to me so I cant build again and again).

The build i want is 

MTC20F     android-6.0.1_r62     Marshmallow     Nexus 5X, Nexus 6P

https://source.android.com/setup/start/build-numbers.html

The drivers available are from 7.1 onward.

https://developers.google.com/android/drivers

I have two questions:

                      1 - Should i just build it without binaries.

                      2 - I also heard that you can extract the binaries from stock ROM (how can do it could not found any helpful resources on it)

Try flashing the vendor.img from the factory image for MTC20F.
