Not sure what you mean, I use x86 docker on my m2 MacBook no problem. Colima makes this fairly trivial

X86_64 containers run just fine on my m2 Mac. Since macOS doesn’t really support containers, it’s really just running a vm to run the containers in. Changing the vm allows you to run a different arch. Rosetta makes that fairly easy. I use Colima to run my containers, and to make them run as x86_64 it’s just a command line flag
