Are you using the F12 dev tools Emulation tab to emulate in IE 11? If yes, you can refer to this article.
Actually, that's a naming issue. Prior to Windows 10 when the Edge browser started, the compatibility modes listed the latest version (version of that browser) as "Edge" in IE. They renamed that setting when Win10 came out. In the article you can also find:
Edge (Default) represents all the latest standards and features IE11 supports.
In your case, you don't need to emulate Edge in IE 11 on Win10, just use IE 11 document mode which is the same thing.
If you want to use Edge browser (not the same thing as Edge mode in IE 11), you can only download Edge browser then use it.
