Touchpad palm detection

Hi I'm running the X1 Extreme Gen 2 on openSUSE Tumbleweed with latest KDE desktop. It is always annoying when typing and one comes close to the touchpad with the palm. It gives in the best case unpredictable results, in the worst case deletes text or unwanted actions. By chance I detected a 'palm detection' setting in the config menu for the touchpad, unfortunately greyed out. Does anyone know if - the touchpad supports palm detection? - what driver is required to enable it? Thanks! Axel
