In AIX there is a file /etc/nologin, which, when in place, prevents any login. (It is deleted automatically upon reboot, so it can't be forgotten.) Maybe there is something alike in RHEL, which you could incorporate to your deployment process to prevent these things? If not: how about killing getty instead? That would also prevent new logins until a final reboot, which should perhaps be the last step in a customisation process anyway.

I hope this helps.
