About low-level parameters control

[noseefood]

Hi, I am a researcher using Clarius. Thank you for your genius product. But I have a problem: In another repo, "clariusdev/raw" 's README file, it seems we could control some low-level parameters such as "steer angle", but in cast API Python's example and cast_def.h file, I could not find the possible interface for "steer angle".
So, I want to know if a Python-based method can control these low-level parameters and, if so, how to enable them. Thank you very much for your help.
