Advanced touchpad features are often handled on a BIOS/chip level so all the OS sees is basic devices doing basic things. If I wagered a guess it’s that it won’t need drivers but that’s definitely a guess.
This is all I have been able to find as it relates to the numberpad/touchpad combo on asus machines and its current status with Linux. Do note this is under Ubuntu and Ubuntu-based Distros. https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1810183
