You can turn off the beep for a single button by replacing the direct command with a one step normal macro (containing the desired command) and an identical press-hold macro. Only the press-hold macro will beep, and the beep can be delayed by up to 5 seconds, it's makes it pretty much gone, unless the user holds the button down for 5 seconds, in which case they'll get a beep with the same effect as if they pressed the original beeping button.
