Parameter tuning in final_estimator with automl ensemble

[Arsa-Nik]

Hello,
When using CatBoostClassifier as the final estimator in FLAML's automl ensemble configuration, are the parameters of final_estimator - CatBoostClassifier() - automatically tuned, or do they default?

"ensemble": {'final_estimator': CatBoostClassifier(), 'passthrough': True}

The parameters of the CatBoostClassifier are not automatically tuned.
Set passthrough to False to automatically tune the parameters.
Thank you
