Quest Toggle

Would like a feature to toggle the quest system on and off. Playing a campaign that was before the new update, and we have our own quest (a long expedition to secure an iron mine, with different hurdles of desert creatures, forts, factions etc in our way) However, because there is no ‘quest’, all my companions constantly throw in random quest hooks, seemingly making up artefacts or points of interests from nowhere, essentially becoming quest givers, and not companion NPCs.
