Low-latency FPV video streaming (<100 ms) via cable on HuskyLens 2

Hello,
I am currently using the HuskyLens 2 from DFRobot and I want to use it for an FPV-style video stream through a wired connection.
My goal is to achieve very low latency (under 100 ms) for real-time control and monitoring.
Current situation:
WebRTC streaming works, but it needs to be manually enabled after every reboot.
I would like a stable low-latency streaming method via cable.
The use case is similar to FPV monitoring, where delay must be minimal.

Questions:
What is the best method to stream HuskyLens 2 video with latency under 100 ms through a wired connection?
Is WebRTC the lowest-latency option, or is there another protocol recommended (RTSP, raw stream, etc.)?
Is there a way to automatically start WebRTC after boot, or an API/command to enable it programmatically?
Are there examples of low-latency video pipelines using HuskyLens 2 for robotics or FPV applications?
Any suggestions or documentation would be greatly appreciated.
Thank you.
