SIP is similar to an enhanced secure boot. It's not (at least not primarily) for DRM.

He might be talking about a Gatekeeper override which is available by digging into the system settings? This allows you to run insecure resigned software (like pirated software is a common use case, honestly). But you only have to do this once, it isn't some constant headache.

I'm not sure what exactly he's referencing, actually. But it can almost all be disabled on macOS (the same is not true of iOS).
