I have nvidia-driver-470 as my main graphic driver, it works for dual-screen monitors. I tried docking to extend to another monitor, but the third monitor is not detected. The dock is connected via USB-C 3.2 port. I tested this configuration in Windows 10, and all three monitors are connected with this setting. This somehow does not for Ubuntu 20.04 and this Asus laptop. Please let me know if there is anything else I can do to connect another monitor.

If both monitors are connected to the USB-C dock, then xrandr outputs as follows.

There are related questions here, here, here, especially here, and here (specifically to Asus) but it doesn't solve my problem.
Notes:
- This works on Windows and Mac, so this must be an isolated Linux problem.
- Ubuntu 21.04 also does not work.
Updates:
- Upgrade to Ubuntu 21.04, it's much more friendly than Ubuntu 20.04 with Wayland enabled.
