SONY IMX390 API to control paramaters

Dear Nvidia support, I am using Sony IMX390 RGGBE5 M3NA110AL0114 and have already contacted Sony asking the questions below, they redirected me to Nvidia support… Could you please help me understand:

  1. Where can I find a list of the camera parameters that are configurable: capture frame rate, capture resolution, exposure time, gamma, … ?
  2. Any C++ API to access and control these parameters ?
  3. Compared to other (non HDR) cameras we use we see that the latency End-to-End with sony HDR camera is about 40 milliseconds greater (all the other components in our system are the same: encoder, decoder, network, …). Is there any parameter we could tune in the camera to try reducing the camera capture time ? What is the expected capture time for this camera ?

Dear @sebastien.venturi,
Note that the ISP tuning for camera is not supported via forum. Please contact your NVIDIA representative if you need ISP tuning. How did you observed the camera latency as 40 msec. Any way to reproduce on our side?
