Weird installation outcome for arm64-sbsa-cross cuda-toolkit

Hi.
I am trying to install cuda-toolkit for cross compiling of ARM64 for AWS-EC2-Graviton2 machine from my Ubuntu 20.04 PC/container.

I followed the installation steps for the “arm64-sbsa” architecture as stated in Nvidia page (further chose Ubuntu 20.04, using local deb file)":
installation-page

I get no errors. But when I look under “/usr/local/cuda-11.8” I don’t see a full installation. specifically nvcc is not installed. All I can see are cuda libs and include-headers installed under “/usr/local/cuda-11.8/targets/sbsa-linux/”.

I will be glad to learn what I am doing wrong here and what is the right way to install cuda-toolkit for sbsa-cross compiling.

Many thanks.
