Roll back Safari from 11.0.2 to Safari 9.1.1

A policy was created to do an Apple update, the update ran by a colleague but due to the nature of the environment a certain version of Safari works to access a specific FTP site. To use the latest version of Safari requires upgrading the subscription with the vendor which my company are not looking to do. Is there a way rolling back that policy?

Rolling back Safari — and especially all the way back to v9.1.1! — will open you up to any number of vulnerabilities that were patched.

If it's an FTP site to which you need access, why not try using Fetch instead?

Rolling back is also becoming more complicated as SIP gets involved on system apps like Safari
