Can we hide UI components for a given subtype of a dataset? For example, I want to remove Lineage, Queries and Stats from showing up on a particular subtype we created?

the UI code will always display those aspects if it is present in the dataset, dont think there is customisation options

Yeah, even if not present, it displays them grayed out
