Even if I knew I wouldn't tell you. Mathioks made it clear that when people do stuff like edit values to get the rinnegan it makes it harder for him to understand what's going wrong in bug reports. The reason you cant even get rinnegan or tenseigan without cheating is because of bugs that they present that he intends to deal with whenever he patches up most major/common bugs in the mod. So just enjoy what the mod has to offer right now instead of trying to just edit a value and get it. I did that with my mangekyo sharingan once and it bugged out then ruined the experience, so I suggest you don't do the same.
Well, I intended to do that in a "sandbox" world, just to play around, but ok then
