How to rotate pen axis to 90 degree in Android 11?

[gordontcp]

Hi all,
How to rotate pen axis to 90 degree in Android 11?
In my system, when I set system to vertical screen, the touch axis it no problem, but pen axis is wrong. The pen axis should rotate 90 degree.
Is there a config file to config stylus to rotate 90 degree? Or should I write a apk to rotate pen axis?
Any suggestion is highly appreciated.
Thanks!
Gordon
