yes you can configure

1 option is to configure stream replication but in such scenario you can only perform fail-over.
2 option is to configure repmgr in which you can perform switchover in postgreSQL

If you mean you want to sync something on CentOS7 with something on
RHEL8 or RHEL9, that's pretty dangerous because glibc's collations
will not be the same [1].  You might get away with doing logical
replication, but don't try physical replication.
