Wacom Bamboo tablet and disabling touch

Hi.
I have a persistent problem with my tablet. I want to totally disable the touch function that interferes with my child’s use of the tablet. I am failing to do this on hers and on my computer (fresh Manjaro here and there).
I tried xsetwacom, xinput, creating a 99-wacom.conf file in etc/X11/xorg.conf.d . Installing the wacomtablet GUI where there is supposedly an option to disable touch also did nothing.
I also checked: modprobe wacom touch_arbitration=0 No effect.
In general, the tablet operation is managed by libwacom from the beginning. Can somehow disable it?
I installed OpenDriverTablet but it doesn’t see the tablet. Maybe the problem is that it is flatpak. I’m afraid to install AURs.
Xserver here.

What?

With a tablet - disabling touch - will render it useless - I mean all interaction with the device is using touch :confounded:

Are you saying you want to disable parts of the input? thus only allowing pen input?

This file would only have effect if the system is use Xorg - and the fact that it doesn’t work could indicate you are using Wayland?

Open Plasma settings > Touchscreen.

I forgot to add that on Mint Cinnamon disabling touch via xsetwacom works fine.

On Bamboo tablets, the touch function applies to hand and finger actions on the tablet’s. This interferes with the use of the pen because the position of the wrist triggers a cursor response. The function is unnecessary and I always turn it off.

It’s not wayland.

echo "$XDG_SESSION_TYPE"
x11

Open Plasma settings > Touchscreen is for gestures, its not Wacom dependent
I use:
System Settings > Input & output > Tablet settings

In Wacom settings there is position to disable touch via keyboard shortcut but it does not working as I mentioned.

I noticed a difference in list devices between Mint cinnamon and Manjaro.
Manjaro is missing Finger touch device:

Manjaro:

xsetwacom --list devices

Mint Cinnamon:

xsetwacom --list devices
