Export pose data as a background service

Hi, we are doing research on pose recognition for VR and would like to use the Oculus quest to get the pose data while letting the participants play whatever game or service they want in the foreground. While we understand the resource limitations of the quest in comparison with PC leveraged systems that makes the quest OS close background applications.
We hope there is a neat trick or tool that would enable this functionality without having to connect the hmd to a computer to run steamVR, which has been the solution so far to get the pose data.
