Magento_Catalog/templates/product/view/attributes.phtml

   if(strpos($_data['value'],"N/A")===false):?>
                <tr>
                    <th class="col label" scope="row"><?php echo $block->escapeHtml(__($_data['label'])) ?></th>
                    <td class="col data" data-th="<?php echo $block->escapeHtml(__($_data['label'])) ?>"><?php /* @escapeNotVerified */ echo $_helper->productAttribute($_product, $_data['value'], $_data['code']) ?></td>
                </tr>
            <?php

            endif;
