why not use TensorRT for LidarBackbone model in CUDA-BEVFusion?

[fsi-kawatawa]

Hello,
In CUDA-BEVFusion, LiDAR Backbone uses ONNX format files (lidar.backbone.xyz.onnx).
Is there any reason why the TensorRT transformation is not performed as in other models (e.g. camera.backbone.onnx)?

This is just because the DDS (data dependence shape) feature is not supported in TensorRT(<=8.x).
