How to implement security profiles during installation of CentOS 8?

I am new to the Linux environment and I found CentOS to be a stable and secure operating system. I do not have much knowledge about the security profiles and how well do they protect the operating systems. I saw many tutorials on YouTube in which everyone skipped the security profiles during installation of CentOS 8 while people installing CentOS 7 used to get an option to select security profiles ( information about it https://wiki.centos.org/TipsAndTricks/C7SecurityProfiles) . The main question I would like to ask, Q1. How do I implement security profiles in CentOS 8? Q2. If we can't use the security profiles of CentOS 7 then what options do we have for CentOS 8? Someone suggested me to use OpenSCAP (info about https://www.open-scap.org/security-policies/) Q3. Will OpenSCAP keep the CentOS 8 secure? Please provide some steps and suggestions which I could implement.
