Making EF Core properties backward compatible with Linq-To-Sql

ASP. NET MVC 4.8 application uses DbLinq. 

Database has tables where column and table names are same:

    CREATE TABLE Product (
       Product CHAR(20) PRIMARY KEY );

Sql to Linq created entites with Contents property from them:

    public class Product (
       public string Contents { get; set; }  
       }

Contents propery becomes part of published API used by third-party applications.

EF Core scaffold creates property Product1 instead:

    public class Product (
       public string Product1 { get; set; }  
       }

This breaks API specification. How to make EF Core with API compatible ?

Is it possible to force it to generate Contents property as Sql to Linq ?

Or is it possible to add additional Contents property which actually gets and sets Product1 property values ?

Npgsql EF Core provider is used in ASP.NET Core MVC application.
