How to Make Some Notifications Completely Silent

I have an HTC 10, obviously. I have my sound set up to vibrate on incoming calls and my default notification sound is silent - so that I don't get audibly notified by every little application. A few applications that I use frequently vibrate on notifications, and I can't seem to turn it off. I want them to be completely silent. I don't want to be notified by anything other than the notification light and seeing the notification on my lock screen. Is there any way to make sure that these notifications don't vibrate? Thanks!
