Howdy!
I wanted to know how I can change some spark configs in a Serverless compute. I have a base.yml file and tried placing: 
spark_conf:
     - spark.driver.maxResultSize: "16g"

but I still get his error:
[CONFIG_NOT_AVAILABLE] Configuration spark.driver.maxResultSize is not available. SQLSTATE: 42K0I

and trying to change a config within the notebook is not allowed either.
