Console command or save Editor to reverse my faction choice

[SuperMedo]

I made mistake by doing the quest The Bronze Beneath the Lake which permanently made me side with the Dozens, it didn't have any warning like Crucible Knight Quest where they warned me doing the quest will make me side with them, I just wanted to do all side quest before siding with anyone.
 
I tried searching global values in save editor couldn't find the value to reverse my decision. 
 
I don't have save file before accepting the quest, what should I do ? is there a solution or I'm basically screwed myself.
