[Cross Compile] Is it possible to build for jetson(aarch64) images on x86_64 machine?

I would like to build a docker container on my x86_64 pc for Jetson aarch64. I tried the following this https://medium.com/@Smartcow_ai/building-arm64-based-docker-containers-for-nvidia-jetson-devices-on-an-x86-based-host-d72cfa535786 and installed QEMU, binfmt_static and then registered using,
docker run --rm --privileged multiarch/qemu-user-static --reset -p yes.
But when I ran run_dev.sh by changing the PLATFORM to aarch64, the aarc64 base image is getting pulled, but later for the next layers it throws an error,

But, I already have the aarch64-ros2_humble-image:latest in my local and I was able to run the aarch64-based container on my x86_64 pc. docker images | grep ros output,

So, I am wondering if is it possible to cross-compile just by changing the PLATFORM variable in run_dev.sh or if am I missing something.
