Lidar Camera hardware trigger

We currently collect lidar and GMSL camera data for 3D object detection tasks, use timestamps for synchronization of data.
We want to use a hardware trigger for better synchronization. For detail, we need to connect trigger pin of lidar (20Hz, will be trigger from low to high when lidar rotates 360 degrees) to Frame sync pin of all MAX96712 Deserializer.
Can we do that?

Dear @v.hieplc,

Unfortunately that GPIO pin on Devkit is not accessible. We will check internally if there is any work around.
