Relocate ./docker/machine folder

I am new to docker and I’m currently looking at the way things are installed.
I run Linux mint V18.1 on a small ssd and because of this I store all large data files e.g Vbox machines on a seperate large HD. I have created a separate partition on this drive for docker development and have succeeded in moving the docker files from /var/lib/docker to this new partition (see docker info printout below). Now though it seems that docker-machine will start to eat up my ssd drive by putting its files in home/.docker/machine. I have tried to find if there is a way of moving this other than by setting up a symbolic link (which seems to be frowned upon by docker) but have had no success - can anyone tell me how to do this.

Thanks in advance
