Is it possible to automatically map and define HashSets as virtual with Scaffold-DbContext command?

Question

In my app, I'm using EF Core with Lazy Loading. Since Lazy Loading requires all HashSets to be defined as virtual , after executing Scaffold-DbContext command to map a DB, I've always edited all single generated file in order to copy-paste the " virtual " keyword before every single ICollection<ClassA> , etc...

In small-DB case, this is not a very time-expensive operation, but it becomes more long-timed as the mapped db grows in terms of number of tables and relations between tables.

So the question is: is there any way to automatically map all HashSets as virtual since the first execution of Scaffold-DbContext command?
Or does it already exist any way to automatically do this operation once the database has been mapped?
