XPS 13 9350 Driver Pack

Hi,  I have been working with Dell engineering, but still wanted to ask the question here.

I have downloaded and imported the XPS 13 9350 driver pack (Win 7 x64). Of course, when you import it, there is driver bloat. But the one I am most interested in is the Realtek Audio driver. It imports over 30 drivers. I know most are not needed, but even so, i didnt remove the ones I and DELL verified weren't installing during SCCM OSD build.  In the past, i have just left everything alone, but was thinking about stripping out everything I know that doesn't PnP.  DELL wasn't sure if the ramifications of doing it and I needed to test.  I have spent 5 weeks on these laptops.

I know others are not a fan of driver packages, specifically for this reason. And they only import what doesn't come with OS source.  i want to use all of the DELL drivers.  This has added about 30-40 minutes to my build process. The longest step in the whole build is the "Apply Drivers" (not auto apply, for that model only).  I just downloaded the latest driver pack that came out and it has a few new drivers, and is even bigger. On my first import, I dont even see those drivers, just the dock usb audio drivers.  Even though i pointed to the entire folder that contains those drivers.  I am currently importing those specific drives to see how they show up. Not sure why they wouldn't have imported in the first place.

Any advice or feedback is appreciated.
