Usually gRPC tries to bump the version of Protobuf every time Protobuf has a new release to make two libraries work together. But gRPC can work with older versions of Protobuf in general. You can try using older protobuf with the latest gRPC. Sometimes you might see build errors because of breaking changes Protobuf sometimes introduced. Note that protobuf introduced two major things recently; new Abseil dependency and Cord support. Those may prevent you from pairing new gRPC and old Protobuf but you can try it.
