Not meant to be snarky, just a tad confused on what exactly you’re asking. Have you ever made an RPM yourself? Dependencies are specified there. Or are you asking about dependencies that don’t exist in standard RHEL repositories?
The parent was saying that specifying dependencies with rpm wasn't possible because they deploy with git but surely they must have something to specify/install deps since a RHEL base likely doesn't have everything they need especially if they're using the system python.
