How to install CUDA 10.2 for Aarch64 (used by Jetson) within l4t-base container?

I found a similar question that already has been answered: Enabling Jetson Containers on an x86_64 Workstation using QEMU

To summarize, software for Jetson cannot be run on x_86 systems (even with docker and qemu) due to the hardware difference. There are ways to cross-compile (e.g. with the CUDA cross-compiler package installed by JetPack on the host), but the software can only be run on the Jetson.
