### What did you do?

The Firehose integration shows a field to customize the output destination.

### What did you see?

### What did you expect to see?

This should not be shown for Firehose.

This issue must be tackled probably exposing a setting in the manifest if the integration supports changing outputs and Fleet UI should not show at all the choice based on the manifest info,
