Docker on ARM Linux doesnt use x86 emulation, I'm not sure why Docker on ARM macOS would.
edit: I am aware not all Docker containers run on aarch64. But that has been changing already, and presumably would accelerate if Apple goes all in on ARM.

macOS is not linux, so it will need some form of emulation/virtualization to run "Docker on ARM macOS"
