NVME WIN 10 Install Fails with Drive not found.

I installed a Samsung SSD 980 in Delta 3. I can not get the USB install procedure to work on the SSD. I am missing a file from the instructions under "The files location on the USB flash drive should be as shown below." The file, ConfigWinPE, is missing. Where can I get that file? The SSD works when I use eMMC to boot. Drive is usable in Windows 10 on Delta 3.
