Not sure at 100% of the use of `FullStack` means, but in a default Symfony app `enable_annotations` is always true.

```bash
php bin/console config:dump-reference framework
```

```yaml
    validation:
        enabled:              true
        cache:                ~
        enable_annotations:   true

    # serializer configuration
    serializer:
        enabled:              true
        enable_annotations:   true
```
