Setting Android 10 Dark theme on and off with adb shell - how to do it without reboot?

To Enable Dark Mode:

adb shell settings put secure ui_night_mode 2

To Disable Dark Mode:

adb shell settings put secure ui_night_mode 1

For Auto Dark Mode:

adb shell settings put secure ui_night_mode 0

and then

adb reboot

My question is how to change Dark mode without abd reboot ?
