Yeah, there's a way to shut off flying, swooping, and throwing. You boot up the mod "The Specialists" and ban all the weapons from the server, then load up an esf map and model. :0(
Not to be rude, but why on earth would you want to do all that? How would you even play?
To answer your question, however, I recall the Developers mentioning in 1.1 that there was a variable to turn off melee. I imagine with melee off there wouldn't be need for swoop either so it might've shut them both off. Of course in 1.2, the cvar might not even be in use...and if it is, it probably wouldn't disable swooping, because swooping is now a defensive move and not requisite of melee.
