Found my answer:
There are three variables you can set, one for init, one for upgrading, and
one for debug messaging.
These can be set when calling postgresql-nn-setup.
No documentation regarding these in the PostgreSQL documentation.
I'm assuming this feature is part of the RHEL/CentOS deploy configuration.

Environment:
PGSETUP_INITDB_OPTIONS Options carried by this variable are passed to
subsequent call of `initdb` binary (see man
initdb(1)). This variable is used also during
'upgrade' mode because the new cluster is
actually
re-initialized from the old one.
PGSETUP_PGUPGRADE_OPTIONS Options in this variable are passed next to the
subsequent call of `pg_upgrade`. For more info
about possible options please look at man
pg_upgrade(1).
PGSETUP_DEBUG Set to '1' if you want to see debugging output.
