Set per-app language with adb shell?

I was looking forward to using per-app languages with Android 13. However, my OnePlus 8T does not feature the necessary settings item for that on OxygenOS 13. Is it possible to set a different language with an adb shell command? adb shell settings get global settings_app_locale_opt_in_enabled returns null, so I'm not sure if it's even implemented at all. Smartphone is rooted with Magisk.
