right after the base OS is completely covered

I suggest to start with the kernel
But please do read up on the various variants and mitigations. You may not necessarily need all of them
Also, you may lack the right firmware/microcode updates from your CPU vendor at the moment. Red Hat's microcode package only contains those which were released by Intel/AMD so far.
