No, not to release. But I rarely use the BAD lever for that purpose anyway, 90% of the time I just use it to lock the bolt back since the thumb falls naturally to press the bolt catch after reloading.
Locking the bolt back, especially during training, malfunctions or competition, is where the BAD lever really shines because it makes things a little less awkward (especially at ranges which frown on raising the muzzle above the berm, I see a LOT of people struggle with that rule).
Whether that's a big enough benefit to purchase and install one is up to the individual. If you're a top-tier competition shooter or door kicker, you might gain some speed using it to release the bolt, but for 99% of us a simple oversized bolt catch will be the better idea. Even a stock one if you want to do that boring practice thing
EDIT: Speaking of oversized, one thing to watch for is that the BAD lever gives a somewhat larger surface area to bump into, so when your rifle is slung it's a little easier to accidentally release the bolt. Just something to be mindful of... probably only an issue when training or competing, since an HD rifle or fighting rifle is hopefully going to have the bolt closed on a loaded chamber.
