Hi ! Can you try to install Docker with Intel chip?
https://docs.docker.com/desktop/setup/install/mac-install/
Or you can try to install Ubuntu on your Mac using a virtual machine like UTM or VirtualBox, or create a bootable USB drive to install Ubuntu alongside macOS (dual-booting) or as the sole operating system. (and check my Ubuntu guide)
Hope it helps!
