I do not know Italian but assuming you mean the option for "Summary Rows Below Details" here is how you turn it on for a Worksheet:

using (var package = new ExcelPackage(fileinfo))
{
    var workbook = package.Workbook;
    var worksheet = workbook.Worksheets.First();
    worksheet.OutLineSummaryBelow = true;
}
