Just installed 5.9rc6 booted up on battery only and touchpad is working but cannot reverse 2-finger scrolling direction.  I'll just keep upgrading the kernel with every release to see what progress we make.  It's still a heck of a Win10 laptop until this get worked out.

https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.9-rc6/amd64/

Whole system responsiveness is still laggy but I think that is may be due to Iris + Nvidia MX350 problems (open and proprietary drivers yield same results).
