No. The whole point to having a "hardcoe" (I think "Epic" "Hero" or "Legend" fits better for a fantasy series) mode shipped with the games is that the people who play on the consoles can vary the atmosphere of the game.
Personally, I'd like the regular game to have realistic fatigue, eating/drinking, sleeping, health, and swimming. If you want to turn those off, you have to select "Pansy" or "Easy" mode.
*A pansy is a flower. If anyone is insulted by "pansy," consider that I avoided "girly" which is sixist, and "sissy" which is only ever used as an insult, and is slightly homophobic.
