No, but its inconceivable that someone who was capable of using Enton woud not be named.Why not?Is it really inconceivable to believe there might have been more MS users than just Izuna or Madara during a time where the Uchiha were constantly at war?The Sharingan evolves when the Uchiha feel immense feelings of sadness or despair,in war they would've lost a lot of close friends and family.
Everything points towards Izuna being capable of using Enton, I don't see why you should ignore it and say a fodder was capable of doing it over Izuna.
