If you are looking for a quieter hub, get Shimano's as they are nearly silent while coasting. My FH-7700 Dura Ace hub makes no noise at all. Shimano even makes a series of hubs intended for Police bikes that are completely silent.

Those who ride Campy, Chris King, etc. hubs claim their infernal racket is a feature, not a bug.

And, no, don't remove pawls from an existing hub.
