I'm not consulting the wiki because I don't want to read too many spoilers

My question is: I want to play as much of the game with both the Institute and the Brother of Steel as friend. I don't mind being enemies with the Railroad, and apparently I'd remain friends with the Minutemen because they don't seem to care which path I follow?

Which quests should I NOT do in order to remain friends with both BoS and Institute?

Thanks.

Don't do Mass Fusion for the Institute. Stop the Brotherhood questline after Tactical Thinking.

There's no way to remain friendly with both if you intend to finish the game.

You can keep any combination alive except for the Institute and the BoS. I really was hoping for some kind of loophole, but since Father is the one to give you the quest, avoiding him is not possible. It's either the BoS or the Institute.

I'm not trying to finish the game remaining friends with both, I know that's impossible. But I would like to know which quests to avoid to play the game as long as possible without becoming enemy of either Institute or BoS.

What about the quests Spoils of War and Liberty Reprimed? Will it affect my relationship with either faction?
