Deepthi Goguri takes us through hint usage in Query Store:
Query Store hints is another amazing feature added and is available in the preview mode in Azure SQL Database, managed instances, elastic pools and hyperscale databases as well. Query Store hints are just like the hints you use in your queries but the difference is you do not have to change the query code to apply these hints using Query store specifically designed stored procedure- sys.sp_query_store_set_hints. Cool, right?
Yes. Yes it is.
