Question School Project: Add external LiDAR to unity

Hi,

For a school project my team and I are aiming to build a measure phone app. But we need to get accurate measure so we want to use an external LiDAR for that.
We consider to use a 360° LiDAR. From this LiDAR we would receive a 2d point cloud where each entry correspond to a distance at a certain angle. I would like to know if it's possible to alter the depth computation directly in ARFoundation or if it's possible to access to the 3d environment object generated by ARFoundation after the computation in order to apply the measure receive from our external LiDAR ?
