Well there is a registry edit that disables ALL vibrate, system wide, but it has a couple of downfalls...... it disables it for calls and everything else and it disables the blinking of your circle button while charging.

On the 6700's 6800's they came stock with the blinking "signal/service" leds, to stop the leds constant blinking, there was a reg edit, but it also disabled Vibrate system wide (tied together for some reason).

Here it is if you want it and don't care about the circle blinking while charging etc.......

[HKEY_LOCAL_MACHINE\DRIVERS\BUILTIN\ALLLEDMGR]
Change "Index"=dword:0
