There is this for Linux but I've never tried it:
I own an nc8430 and a ZBook 15 first generation. I use the lower row of three mouse buttons as left, middle and right click. Those touchpads don't move and don't bend. I disabled tap to click as buttons are much better and never move accidentally the pointer by design. Palm detection works very well, basically no issues. I use two finger scroll and pan. Several gestures work but I don't really like them. I disabled everything. I rather use keyboard shortcuts. I defined some of my own especially to navigate among virtual desktops.
There is still one ZBook Fury model with buttons, every other model lost them.
I've not had to configure anything to make this work for a number of years now in Plasma. Though I've been running Linux on Macbooks for a long time, so maybe it's about specific hardware support.
