Docker is not magic, just extract the contents an OCI image[1] and run it with your favorite container runtime, like cri-o[2]. Or use the docker or OCI inage with podman[0].

And if containers are the problem then unpack the image into it's contents, take the binary, relink it and run it on bare metal.

(Nothing against the FSF, but "dealbreaker" is a very relative concept.)

Docker is never required by anything, it just makes communicating software dependencies simple and concise.
