Thanks. I think EnvironmentFile is just used for setting the environment file of the running process. Setting ARGS in /etc/default/prometheus seems to add the value to the command line arguments, as well as to an environment variable called ARGS for the prometheus process. I can't find any mention of this in the systemd or prometheus docs, but it works.
