After R&D , found the answer

var graphServiceClient= new GraphServiceClient(
                      new DelegateAuthenticationProvider(
                         (requestMessage) =>
                         {
                             requestMessage.Headers.Authorization = new AuthenticationHeaderValue("Bearer", response.access_token);
                             return Task.FromResult(0);
                         }));

graphServiceClient.Users["serviceprincipal"].Photos["64x64"].Content.Request().GetAsync().Result
