Technically, it probably is possible but it would require editing the save to accomplish. It's likely that the quest unlocks don't specifically rely on quest data and status to be "accessible" in menu, so it would be a matter of taking a fully unlocked save, comparing it to a new save, and reverting things until you can figure out which section is saves in order to reset those to the start.
Basically, far more work (for the person doing it) than just playing through the game.
