How to switch back from Oracle Kernel to RedHat?

Hello friends,

We have RHEL 7.5 server with latest updates. We needed to install Oracle 12 DB on it so chose "easy method" of installing "oracle-database-server-12cR2-preinstall-1.0-3.el7.x86_64.rpm" and then installed oracle DB. Everything went smooth and all OK but later we noticed that it has Oracle Kernel ver 4.14 uek installed instead of using Redhat's 3.10 ver. and using updates from Oracle rep. I managed to configure it back to use updates from Redhat (as we have support from RH) but not sure how to switch the kernel back to Redhat's by keeping all the software (esp Oracle) intact. Redhat is NOT providing any support as this server running Oracle kernel.

We can see both Oracle kernel entries & Redhat entries in grub.conf but not sure If I can simply boot Redhat 3.x kernel with oracle too working fine.

Could anyone please advise how to switch back to RH kernel without breaking anything else? I know rebuilding the server from scratch and not choosing "preinstall rpm" method will fix that but that's a too long process.

Many Thanks!
