You could write an extension method to override the names of all columns;

   public static WithPrefix(this OwnedNavigationBuilder builder, string prefix) where T:class where R:class
   {
      foreach (var p in builder.OwnedEntityType.GetProperties())
         p.SetColumnName($"{prefix}{p.Name}");
   }

   .OwnsOne(e => e.Address, cb => cb.WithPrefix(""));
