I tried to find the device manufacturer for the Touchpad using the Device ID mentioned in the Device Manager, but it was in vain. So I have requested in IGG to mention the Manufacturer and Make of the Touchpad and asked them to provide the device driver specific to the Touchpad so that Windows 10 precision Touchpad controls can be modified in order to disable the Tap-To-Touch function.
But at the moment you can try to decrease the touch sensitivity if you would like to and see if that helps as a workaround.
Go to Windows Settings > Devices > Touchpad (You can even search for Touchpad setting using Windows search) and make Touchpad sensitivity to Low Sensitivity.
