E1C65x64 NIC Drivers Cannot be Added to Driver Packages in WDS - Failed Packages error screen

Hello,  I hope I am posting this in the correct forum, navigating the Dell Community forums is a bit confusing to me. 

I hope you can help me with this. I am attempting to add Windows PE NIC drivers to my boot image to support Windows 10 deployment to our new Dell Optiplex models. We are deploying Windows 7 images to Optiplex 3040 and 5570 currently. I have no trouble deploying Windows 7 images to these computers.

I am trying to add the WinPE - Windows 10 version NIC drivers E1C65x64.inf, E1D65x64inf, and E1R65x64.inf in WDS - Add Driver Packages. I have done this before with other Dell drivers for Windows 7 but when I try to add these versions to support Win PE 10 it fails stating they are unsigned or corrupted (screen shot below). I downloaded and extracted these drivers directly from Dell, they are part of the Win PE Driver Pac for the models I am using. 

FYI the version of MDT we are running is the latest one, 8443 on a VMWare Windows Server Standard 2008 R2 server. The latest ADK for 1703 is also installed.  I can Capture and Deploy Windows 7 images w/no problems to the same model Dell computers.

I appreciate your input.
