I answered this already yesterday on the user mailing list. 

I do not think we have any files like that. It often doesn't make sense to use all the different options or it is even impossible. So we do not maintain any such files. The documentation has the API reference where you can find all the options: https://strimzi.io/docs/operators/latest/using.html#schema_properties 

You should be also able to find the OpenAPI schema in the CRDs.

Thanks & Regards
