Currently not available, you can try to upgrade the system to the 1909 version, or directly download the pure version of the Microsoft official website to install, and then you can contact our after-sales mailbox to obtain the driver
Thanks. Strangely, I managed to get upgraded to 1903 via MS updates at the third attempt. It then upgraded to 1909 at the first attempt after that. It seems if the update fails, just keep trying. Working great now.
