CUDA installation on ORIN NX

I wanna install TensorRT and CUDA 11.4 on reComputer J4012 (Jetson ORIN NX 16GB)
J4012 doesn’t be recognized by SDK manager of host PC so I guess I should install them manually.
But at the links below, I cannot find download for aarch64, Can I use files for ARM-SBSA?
Or can someone help me what to do?
