Thanks a lot @SparkJun , In documentation I am not able to find answer to one scenario 

Let's say we have explicitly disable predictive optimization for a Catalog named "CatalogXYZ" and then after that we have enabled this at Account level. Later a user who is the owner of Schema named "CatalogXYZ.TestSchema" can enable the predictive optimization for this schema or not because it was disabled explicitly for parent Catalog?
