No arm64 of os-docker?

I tried to switch my engine to run docker-17.06.1-ce but my raspberry pi 3s that is running rancheros-arm64 failed because there is no arm64 tag of the rancher/os-docker. Is this on purpose and is there some workaround or do I need to re-install the OS in 32-bit versions?

It’s because docker changed the build system dramatically for the moby
fork, and we haven’t had time to work on that

things look like they’ll get better in future - there’s a 17.7 aarch64
