Bitrix ORM: Как использовать JOIN, чтобы сократить количество запросов?

use Bitrix\Iblock\ElementTable;
use Bitrix\Iblock\PropertyEnumerationTable;
use Bitrix\Iblock\ElementPropertyTable;

$idArray = [];
$resultObj = ElementTable::getList([
  'select' => ['ID'],
  'filter' => ['IBLOCK_ID' => 1, "IBLOCK_SECTION_ID" => 1, 'ACTIVE'=>'Y'],
]);
while ($rowArray = $resultObj->fetch()) {
  $idArray[] = $rowArray['ID'];
}

$idElementArray = [];
$resultObj = ElementPropertyTable::getList([
  'select' => ['VALUE'],
  'filter' => [
            'IBLOCK_ELEMENT_ID' => $idArray,
            'IBLOCK_PROPERTY_ID' => 1
        ], 
]);
while ($rowArray = $resultObj->fetch()) {
  $idElementArray[] = $rowArray['VALUE'];
}

$resultObj = PropertyEnumerationTable::getList([
  'select' => ['VALUE'],
  'filter' => ['ID' => $idElementArray],
]);
while ($rowArray = $resultObj->fetch()) {
  $arResult[$rowArray['ID']] = $rowArray['VALUE'];
}
