The Gopro Max is a 360° hobby camera that was developed for hobbyists and primarily videos, in order to bring 360° videos into the price range.
Writing your own software for it could still be very tricky, depending on your previous knowledge. For the Hero cameras, there is software from Rocksteady for stabilised videos from the 4th or 5th generation (before Hypersmoothe).
So I would imagine that there could be a third party software for the MAX somewhere, possibly with HDR mode. The best place to look is Github (
https://github.com/). Or ask Google.
Hope you find something and happy new year 😊
