I don't know what the manufacturer of your touch pad is. Asus looks to be using some proprietary stuff.
What I recommend is look 2 places:
Look for Asus Smart Gesture or Control Panel --> Touchpad or Control Panel --> Mouse (something like that).
You can customize sensitivity using either of those 2.
However, I think it may be the smart gestures that are annoying you. You can look into turning those off.
Make sure you downloaded the [http://dlcdnet.asus.com/pub/ASUS/nb/Apps_for_Win10/SmartGesture/SmartGesture_Win10_64_VER4012.zip?_ga=2.45918625.408779087.1517432466-176881019.1517432466|latest version].
