How do I turn off a touchscreen on Acer?

I have an Acer laptop with touchscreen function, but my screen is broken or has a crack which makes it impossible to click on something because it clicks on the crack because of the touch function. My question is how can I deactivate the touchscreen function without clicking on anything or even better with a key combination.

Would be good if you would name the laptop, you could then help specifically.

Sorry, misunderstood.

It should be right here:
