Yep ... If you have the manual in the glove box it's on page 5-151. The quick answer is to press the multi-informational display selector button (That's the long version of the menu button to the lower left of the instrument cluster) until you get to settings. Then scroll through the settings until you get to turn signal sound and set it to the other sound. It's defined as Sound 1 and Sound 2. 1 is the traditional clicking sound and 2 is the annoying beep.
