not sure why i'm seeing grpc blocking the event loop so often

### Problem description
i tried to turn on event loop block detection, and all i see are grpc calls (we use google pubsub and other grpc-using tools), which doesn't make sense to me, since i thought during the call the system should yield

### Reproduction steps
Use grpc on a busy server (we use google secrets manager, google pubsub, etc.)

### Environment
- Linux Ubuntu 18.04 amd64
- Node 18
- nvm/yarn

### Additional context

Examples:

```

8: " at process.processTicksAndRejections (node:internal/process/task_queues:95:5)"
message: "Event loop blocked for 600.4265230000019ms, operation started here:"
```

```

"message": "Event loop blocked for 99.32906599998473ms, operation started here:"
```

basically most of my event loop is blocked on grpc stuff. is there some configuration or setting to make it properly yield?
