My Google Chromecast with Google TV is running Android Q (10) and I want to integrate it into my home automation system which is possible (https://www.home-assistant.io/integrations/androidtv/)
However the stick needs to run Android 9 as Android 10 has introduced a SELinux policy that stops certain commands from being executed.
How can I downgrade my stick to Android 9?
