Cancellation of the deactivation of sections missing in the unloading from 1C?

Question

1C-Bitrix

The site has separate sections for linking products. These sections are not in 1C and will not be. When you start a full unload, after the exchange, the partitions are deactivated.

The option - What to do with groups missing in the import file: nothing is enabled in the site settings.

I tried to disable it in the handler (init.php) and the exchange still disables the section.

AddEventHandler("iblock", "OnBeforeIBlockSectionUpdate","DoNotDeactivate");
function DoNotDeactivate(&$arFields)
{
   if ($_REQUEST['mode']=='import')
 {
      $arFields['ACTIVE'] == "Y";
   }
}

#Отмена отключение по свойству тип UF

AddEventHandler("iblock", "OnBeforeIBlockSectionUpdate","DoNotDeactivate");
AddEventHandler("iblock", "OnAfterIBlockSectionUpdate ","DoNotDeactivate");
function DoNotDeactivate(&$arFields)
{
   
   if ($arFields['UF_TAGS'] == 1) {
      unset($arFields['ACTIVE']);
   }
}
