Thank you for posting in Microsoft Q&A forum.
Based on a lot of research, there are some limitations on the parameter. The main parameters are listed on the documents, unfortunately, the /N parameter exact answer is unavailable. I also tried this command in my lab environment, it could run without /N parameter. Maybe this parameter is optional.
We could refer to this article to search other parameters:
operating-system-deployment-createmedia.exe
Thank you for your understanding and have a nice day!
