No Vibrate During Calls

Is there a way to get my phone to not vibrate during calls? I want it to vibrate for various notifications when I'm not on a call, but it's a bit startling with my phone up to my ear. I've found a few SMS apps that can do it, but I'm hoping for something general, across all notifications. Upon further testing, it seems that my phone (Moto G, Android version 5.1) doesn't vibrate during a call by default. But sometimes, it messes up and allows the notification vibration to go through.
