Is there a dedicated touchscreen driver for chromeos? How do I get it?

There are kernel drivers that handle individual touch controllers, but once the data is converted to linux event stream (https://en.wikipedia.org/wiki/Evdev) it is consumed by Chrome. You probably want to start looking here: https://source.chromium.org/chromium/chromium/src/+/main:ui/events/ozone/evdev/touch_event_converter_evdev.cc

Does chromeos support 20-point touch? If so, how do I get support?
