Set-IniValue without -section parameter

we have an ini File without a section in this file.
When i don´t use the parameter -section i will get an error.
Is it possible to use set-inivalue without -section?

It doesn’t seem like this is possible. I tried changing the function parameter $Section so it wasn’t mandatory, and when I did that, it created an empty section- []. Does it matter where in the file the entry is? Could you just use add-content to add it to the end of the file?

Add-Content -Value “nrtest” -Path “C:\windows\win.ini”
