A working option for filtering the entire catalog (bitrix:catalog.smart.filter in sections.php)?

Question

1C-Bitrix

Good afternoon!
The task is as follows: display all the products of the catalog in the root of the catalog with the possibility of filtering them through bitrix:catalog.smart.filter.
I tried all the options from the TOP queries on the question, but nothing works if the CNC is enabled.

As a result, this filter code worked + specify in the catalog.section parameters after the filter
"BY_LINK"=> "Y",
"SHOW_ALL_WO_SECTION" => "Y",
"SECTION_ID" => '0',

<?
      $arFilter = array(
        "IBLOCK_ID" => $arParams["IBLOCK_ID"],
        "ACTIVE" => "Y",
        "GLOBAL_ACTIVE" => "Y",
      );
      if (0 < intval($arResult["VARIABLES"]["SECTION_ID"])) {
        $arFilter["ID"] = $arResult["VARIABLES"]["SECTION_ID"];
      }
      elseif ('' != $arResult["VARIABLES"]["SECTION_CODE"]) {
        $arFilter["=CODE"] = $arResult["VARIABLES"]["SECTION_CODE"];
      }

      $obCache = new CPHPCache();
      if ($obCache->InitCache(36000, serialize($arFilter), "/iblock/catalog")) {
        $arCurSection = $obCache->GetVars();
      } elseif ($obCache->StartDataCache()) {
        $arCurSection = array();
        if (Loader::includeModule("iblock")) {
          $dbRes = CIBlockSection::GetList(array(), $arFilter, false, array("ID"));

          if(defined("BX_COMP_MANAGED_CACHE")) {
            global $CACHE_MANAGER;
            $CACHE_MANAGER->StartTagCache("/iblock/catalog");

            if ($arCurSection = $dbRes->Fetch()) {
              $CACHE_MANAGER->RegisterTag("iblock_id_".$arParams["IBLOCK_ID"]);
            }
            $CACHE_MANAGER->EndTagCache();
          } else {
            if(!$arCurSection = $dbRes->Fetch()) {
              $arCurSection = array();
            }
          }
        }
        $obCache->EndDataCache($arCurSection);
      }
      if (!isset($arCurSection)) {
        $arCurSection = array();
      }



      $APPLICATION->IncludeComponent(
        "bitrix:catalog.smart.filter",
        ".default",
        array(
          "PREFILTER_NAME" => $arParams["FILTER_NAME"],
          "IBLOCK_TYPE" => $arParams["IBLOCK_TYPE"],
          "IBLOCK_ID" => $arParams["IBLOCK_ID"],
