How can I implement SQL and SQLite simultaneously wihtout big if statement

HI lets say I have a C# code

private const string INSERT = "INSERT INTO Person VALUES (@FirstName, @LastName)";

public static DbCommand INSERTCOMMAND(IPerson person)
{
    DbCommand command = null;
    var sqlParams = new List<DbParameter>();

    if(SQLManagerFactory.SQLManager is SQLServerManager)
    {
        command = new SqlCommand(INSERT);
        sqlParams.Add(new SqlParameter("@FirstName", person.FirstName);
        sqlParams.Add(new SqlParameter("@LastName", person.LastName);
    }
    else // SQLiteManager
    {
        command = new SQLiteCommand(INSERT);
        sqlParams.Add(new SQLiteParameter("@FirstName", person.FirstName);
        sqlParams.Add(new SQLiteParameter("@LastName", person.LastName);
    }

    command.Parameters.AddRange(sqlParams.ToArray());
    return command;
}

Which is working perfectly fine. Of course in my production code, it is quite bigger and has a lot more location that does the similar things for different commands.

My question is that is there way to make this shorter? I do not wish to copy and paste code which essentially does the same thing except for calling the different constructors.

Thank you very much in advance.
