This guide does not clearly identify which architectures are supported for the agent based installer.  It appears to be x86_64 only, but not clear for other architectures like ppc64le, s390x, arm.   Most of it doesn't mention any specific arch, but then there's a note about FIPS only being on x86_64 right now. But then if you try to download the OCP installer for this agent-based installer the choice of platform is greyed out and thus locked to only be x86_64, thus implying this isn't for any other arch at all.
