Yes bro I know you don't need all the default buttons, there is a set of configurations that you can use to remove them. Custom In-Room Control panels can still be exposed. Removing default buttons and adding custom buttons makes it possible to fully customize the user interface.
For example, remove the Call and Share buttons if nobody is going to share content or call from this device. Then, add custom buttons (In-Room Controls) for the tasks that users are going to perform. Use the following configurations to remove default buttons from the user interface. The configurations are available from the web interface of the device and in the API
