How to Replace a Layer in a ManagedRuntime with Another Implementation

const makeMyService = {
  someFunc: () => Effect.succeed("dummy")
}
export class MyService extends Context.Tag("app/MyService")<MyService, typeof makeMyService>(){
  static Dummy = Layer.succeed(this, makeMyService)
  static Live = Layer.succeed(this, {
    someFunc: () => Effect.succeed("real")
  })
}

const runtime = ManagedRuntime.make(Layer.mergeAll(MyService.Dummy));

const program = Effect.gen(function*() {
   const myService = yield* MyService;
   yield* myService.someFunc();
});
// can I swap the MyService to use Live instead of Dummy?
runtime.runPromise(program)
