3D Tracking in Deeplabcut

I’m interested in using DLC for analyzing 3D data (from 3 orthogonal cameras). Calibration using a checkerboard might not work as we have high light requirements, so I was wondering if there is a way to provide the camera parameters (I’m using DLT calibration to DLC) instead of having DLC do that calibration?

Also, is there demo 3D which I can use to get an idea of how to use DLC in 3D?

Here is the documentation and demo for 3D deeplabcut:
