First, download and install:
Download the Windows ADK for Windows 10, version 2004

Second, download and install
Download the Windows PE add-on for the ADK, version 2004

or run:

C:\WINDOWS\system32\cmd.exe /k "C:\Program Files (x86)\Windows Kits\10\Assessment and Deployment Kit\Deployment Tools\DandISetEnv.bat"

No matter what type of media you're going to create, the first thing to do is create a working set of WinPE files on your technician PC.

Create a bootable WinPE USB drive.

MakeWinPEMedia will format your WinPE drive as FAT32. If you want to be able to store files larger than 4GB on your WinPE USB drive, you can create a multipartition USB drive that has an additional partition formatted as NTFS. 
Use MakeWinPEMedia with the /UFD option to format and install Windows PE to the USB flash drive, specifying the USB key's drive letter:

MakeWinPEMedia /UFD C:\WinPE_amd64 D:

Create a WinPE ISO, DVD, or CD

Use MakeWinPEMedia with the /ISO option to create an ISO file containing the Windows PE files:

MakeWinPEMedia /ISO C:\WinPE_amd64 C:\WinPE_amd64\WinPE_amd64.iso
