In addition to @briddums' answer, since EPPlus version 5 you can ignore errors and there is no need to touch the EPPlus source.

var p = new ExcelPackage();
var ws = p.Workbook.Worksheets.Add("IgnoreErrors");

ws.Cells["A1"].Value = "1";
ws.Cells["A2"].Value = "2";
var ie = ws.IgnoredErrors.Add(ws.Cells["A2"]);
ie.NumberStoredAsText = true;   // Ignore errors on A2 only

this code works

private void removingGreenTagWarning(ExcelWorksheet template1, string address)
            {
                var xdoc = template1.WorksheetXml;
                //Create the import nodes (note the plural vs singular
                var ignoredErrors = xdoc.CreateNode(System.Xml.XmlNodeType.Element, "ignoredErrors", xdoc.DocumentElement.NamespaceURI);
                var ignoredError = xdoc.CreateNode(System.Xml.XmlNodeType.Element, "ignoredError", xdoc.DocumentElement.NamespaceURI);
                ignoredErrors.AppendChild(ignoredError);

                //Attributes for the INNER node
                var sqrefAtt = xdoc.CreateAttribute("sqref");
                sqrefAtt.Value = address;// Or whatever range is needed....

                var flagAtt = xdoc.CreateAttribute("numberStoredAsText");
                flagAtt.Value = "1";

                ignoredError.Attributes.Append(sqrefAtt);
                ignoredError.Attributes.Append(flagAtt);

                //Now put the OUTER node into the worksheet xml
                xdoc.LastChild.AppendChild(ignoredErrors);
            }

use it as

removingGreenTagWarning(template1, template1.Cells[1, 1, 100, 100].Address);
