No. You definitely need to initialize the database cluster before you try
starting it.

After some searching I found this:

https://git.postgresql.org/gitweb/?p=pgrpms.git;a=blob_plain;f=rpm/redhat/master/non-common/postgresql-10/master/postgresql-10-README-systemd.rpm-dist;hb=HEAD

The section titled: "MULTIPLE POSTMASTERS (For the same PostgreSQL version)"

Though, if you don't care about systemd just ignore all the RPM-specific
stuff and follow the instructions in the PostgreSQL documentation. IOW,
don't use "postgresql-10-setup".
