Disable touch screen Ubuntu 20.04 Huawei matebook pro

I'm trying to disable the touch screen on my huawei matebook x pro laptop, due to a crack in the screen corner. This makes my cursor go crazy, with random mouse clicks where the crack is.

I've tried:

xinput --list

where I get:

⎡ Virtual core pointer                      id=2    [master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer                id=4    [slave  pointer  (2)]

I can't see anything related to touch screen here.

I've also tried to disable the drivers by uncommenting in

/usr/share/X11/xorg.conf.d/70-wacom.conf

# "tablet", "touchscreen", and "touchpad" to ensure that the Wacom
# driver is not accidentally bound to other types of hardware that
# Wacom has made which are not handled by the wacom driver (e.g the
# Wacom Bluetooth Keyboard)

This doesn't help either.

Any suggestions?
