Do something like this:

    mkdir -p /etc/systemd/system/foo.service.d/
    cat > /etc/systemd/system/foo.service.d/override.conf <<EOF
    [Service]
    ExecStart=
    ExecStart=/path/to/my/command --with=a --new-commandline
    EOF
    systemctl daemon-reload
    systemctl restart foo.service

i.e. add a drop-in that first resets ExecStart= to the empty list, and
the writes the new cmdline to use into it.
