Debug non-debuggable packages on Streamline

Based on this question, it seems that third-party apps are by default non-debuggable. It is mentioned, however, that the device needs to have a non-release version of android. I have purchased a Qualcomm development board that has a userdebug build on it. The only package that is debuggable is the telemetry service package from Qualcomm.

Are there any alternatives for other packages? How could I start a capture and get statistics for other programs like Geekbench and Spotify?

Thanks.
