Is there anyway to make mobs not attack you while playing in survival mode in minecraft edu?

Me and my friend are building some type of a RPG game in Minecraft: Education Edition and we were trying to figure out how to make mobs nonhostile while in survival and in normal mode.

I searched up commands and stuff like that but nothing worked.

I had tried the /scoreboard teams command as well, but yet, it didnt work either cause you cant use the team part in edu

any help here?
