Not really, as the man page (that Michael already linked) states [0] using Storage=volatile will cause the journals to be stored only in memory (under /run/log/journal) without any disk writes. You can also disable journal completely using Storage=none, in which case journald would work only as a forwarder to syslog/kmsg and other configured services (if present). Again, I'd recommend going through the Storage= docs in the respective man page[0].
