How to make a filter only at the last level of the product catalog in 1s Bitrix?

Question

1C-Bitrix

Help, please, to solve the problem. It is necessary that in the product catalog the filter is shown only at the last level. The level of nesting in the catalog is different in different subgroups. Here is the part of the section.php file that is responsible for the output of the filter (in my opinion).

// set offer type & smartfilter view
    $typeTmpSKU = $viewTmpFilter = 0;
    if($section['UF_OFFERS_TYPE']){
        $typeTmpSKU = $section['UF_OFFERS_TYPE'];
    }
    if($section['UF_FILTER_VIEW']){
        $viewTmpFilter = $section['UF_FILTER_VIEW'];
    }
    if(!$typeTmpSKU || !$viewTmpFilter){
        if($section['DEPTH_LEVEL'] > 1){
            $sectionParent = CNextCache::CIBlockSection_GetList(array('CACHE' => array("MULTI" =>"N", "TAG" => CNextCache::GetIBlockCacheTag($arParams["IBLOCK_ID"]))), array('GLOBAL_ACTIVE' => 'Y', "ID" => $section["IBLOCK_SECTION_ID"], "IBLOCK_ID" => $arParams["IBLOCK_ID"]), false, array("ID", "IBLOCK_ID", "NAME", "UF_OFFERS_TYPE", 'UF_FILTER_VIEW'));
            if($sectionParent['UF_OFFERS_TYPE'] && !$typeTmpSKU){
                $typeTmpSKU = $sectionParent['UF_OFFERS_TYPE'];
            }
            if($sectionParent['UF_FILTER_VIEW'] && !$viewTmpFilter){
                $viewTmpFilter = $sectionParent['UF_FILTER_VIEW'];
            }

            if($section['DEPTH_LEVEL'] > 2){
                if(!$typeTmpSKU || !$viewTmpFilter){
                    $sectionRoot = CNextCache::CIBlockSection_GetList(array('CACHE' => array("MULTI" =>"N", "TAG" => CNextCache::GetIBlockCacheTag($arParams["IBLOCK_ID"]))), array('GLOBAL_ACTIVE' => 'Y', "<=LEFT_BORDER" => $section["LEFT_MARGIN"], ">=RIGHT_BORDER" => $section["RIGHT_MARGIN"], "DEPTH_LEVEL" => 1, "IBLOCK_ID" => $arParams["IBLOCK_ID"]), false, array("ID", "IBLOCK_ID", "NAME", "UF_OFFERS_TYPE", 'UF_FILTER_VIEW'));
                    if($sectionRoot['UF_OFFERS_TYPE'] && !$typeTmpSKU){
                        $typeTmpSKU = $sectionRoot['UF_OFFERS_TYPE'];
                    }
                    if($sectionRoot['UF_FILTER_VIEW'] && !$viewTmpFilter){
                        $viewTmpFilter = $sectionRoot['UF_FILTER_VIEW'];
                    }
                }
            }
        }
    }

Endless monitoring of Google and Yandex did not answer my question. php in 1s-bitrix is ​​just starting to master.

It is necessary to wrap the call of the filter component in a condition.

if($section['RIGHT_MARGIN'] - $section['LEFT_MARGIN'] == 1)  {
    // компонент фильтра
}

According to Bitrix logic, such a condition will always tell you that the subsection of the last nesting level
