AFAIK, it wasn't an option in the version I played years ago. If I could play in third person, I'm guessing it wouldn't make me motion sick at all (though there are exceptions), but since I didn't find the game itself appealing, I haven't bothered to look into ways I could play it without motion sickness. I'm not a fan of open world/sandbox games in general. I know it's used as a dirty word in gaming these days, but I actually like "linear" games.
