The rating tool can be seen in the UI when building from main Branch. Therefore an "Average rating" that does not contain any data can be seen. In addition, the user can rate, but that has no impact (since there is no backend for rating).
Can it be disabled? It is an unfinished, not working feature that should not be visible at all.
There should be an option to disable this feature even if it would work. Since there are environments where this feature is not needed or needs introduction before being made available.
