i want edit username or public name ?
You can use this plugin GitHub - mitodl/edx-username-changer: A plugin to enable update usernames through admin panel in Open edX (and other apps that log into Open edX via OAuth)
supports Open edX Nutmeg Release?
In the git repo the author wrote:

So it works on Nutmeg.
