Need Help Editing Structure NBT of this mod

I am trying to make it so the trial spawners from the Trials mod spawn Breezes from Familiar Faces instead of the Trials version of Breezes. I do not know how to edit structure data, and the files for the spawners of the Breezes don't seem to contain anything for the trial vault itself. Help would be deeply appreciated. https://www.curseforge.com/minecraft/mc-mods/trials-chambers-backport
