You cannot disable journal but you can reduce it and the following 
should give the least amount of logging in all potential scenarios and 
usage ;)

Just create "/etc/systemd/journald.conf.d/10-hpc-tweaks.conf"which contains

[Journal]
Storage=none
MaxLevelConsole=emerg
MaxLevelStore=emerg
MaxLevelSyslog=emerg
MaxLevelKMsg=emerg
MaxLevelConsole=emerg
MaxLevelWall=emerg
TTYPath=/dev/null

Then restart the journal ( systemctl restart systemd-journald )
