OK, as far as libinput is concerned any function with "n/a" next to it means it does not exist on this device and therefore it is not configurable. https://wayland.freedesktop.org/libinput/doc/1.11.3/tools.html Now, if you/the manufacturer state there is a certain function available and it should be configurable, then it is a question why this is not exposed by the driver/firmware to the kernel and libinput. Libinput developers have stated they will not put effort into features of less common input devices, so I suppose there's that as a potential explanation. If a function and setting is shown in the GUI of XFCE4 but not in Plasma's SystemSettings, you could try comparing the GUI settings in Plasma-Wayland Vs Plasma-Xorg and add what is missing in '/etc/X11/xorg.conf.d/40- libinput.conf'. I don't know if settings configured in 40-libinput.conf will thereafter make them visible in the GUI, but either way it may provide a workaround.
