kernel – How could I fix my touchpad SYNA3602 driver?

I have a Vaio Fe14 (Ubuntu 20.04, kernel 5.8.0-48-generic) that comes with SYNA3602 touchpad. This touchpad isn’t recognized in many distros because of some kernel issues. It seems to work fine in kernel 4.19.

I am using a shell script that solves 95% of my problems with the touchpad, but the system doesn’t recognize the click of left button and sometimes the pointer freezes.

So, there is a way that I can customize my driver/kernel to make it works completely?

This shell script perhaps can help people with the same touchpad!
