Yum update to specific release from a local repository

Hello,

We maintain local RHEL repositories because there is no Internet access in the data center. The repositories were created (from a machine with Internet access) using commands similar to these:

reposync --downloadcomps --download-metadata --arch=x86_64 --repoid=rhel-7-server-rpms --delete --download_path=/var/repos/7/
createrepo -s sha256 --checkts --update --workers=2 -g  /var/repos/7/rhel-7-server-rpms/comps.xml /var/repos/7/rhel-7-server-rpms

Did not pass

newest-only

Servers have to be running specific releases for application compatibility.

yum --releasever=7.3

distroverpkg=redhat-release

Is there a way to "yum update" 7.3 and 7.4 servers from the above repositories without ending up with 7.5?

If

versionlock

Thank you
