You're attempting to use
HasDiscriminator in the wrong context. It is something you would use when you're configuring an entity, not a relationship.
modelBuilder.Entity<SomeType>(b => b.HasDiscriminator(...))
Not sure if there is an easy way to handle discriminators when configuring owned entities.https://github.com/dotnet/efcore/issues/29659 a relevant github issue, not sure if there's been much done to make this easier
