Hi I am trying to run code in example/cuda, but it failed to find those 2 modules, and it's strange that on docs it's in default feature.

Looks like your OpenCV installation doesn't have CUDA support that's why those modules are missing. To include CUDA support you most likely need to build OpenCV manually. Pre-built binary packages rarely contain it.
