can supports grpc server enabled by config

i dependency grpc-spring-boot-starter in pom and i want to enabled/disabled grpc server in cofig like this:

```
grpc:
server:
port: 0
enabled: false
```

can supports the param grpc.server.enabled in future?

Start by inspecting the grpc-spring-boot-starter configuration and the gRPC server startup path referenced by the dependency. Trace how grpc.server.port is currently read, then determine where an enabled property and its false behavior should be covered. Done means the YAML setting can disable or enable the server without changing the existing port configuration, with tests covering both states.
