There hasn’t been anything like that on macOS. macOS on Apple Silicon will have a form of kernel patch protection, like on iOS, but it’s designed to guard against exploits from userland, not approved kexts. It’s definitely possible for third party kexts to bypass that somehow, but possibly only by disabling Secure Boot; I haven’t looked into it.
