The only tip I can give, is that I tried @ferenc's fix while I was running 5.8.0 kernel.
It was working as expected with the regular problems.
Then I've had some issues with Virtualbox-dkms and needed to go back to 5.4.0-47 kernel version.
Suddenly Ubuntu detects the trackpad flawlessly.

Good luck.
