Unsolved WDS - Install Unsigned Drivers

---

I cannot add Windows 10 LAN driver packages to WDS Driver Packages. They are Lenovo drivers. I also tried installing my Motherboard LAN drivers for a VM. Both fail to install the packages. It looks like it is because they aren't signed. Any thoughts anyone??

As a work around I used DISM 10 and added the drivers to the image, but can you use the WDS snap-in to add unsigned drivers?
