Hi,
There is no option for that.
However, it's possible if you customize the product / compare view file via the menu Display>Views.
The code should be fairly simple:
<!-- BRAND -->
<tr id="hikashop_compare_tr_brand">
<td class="hikashop_compare_brand_first_column"><?php echo JText::_('MANUFACTURER'); ?></td>
<?php
$categoryClass = hikashop_get('class.category');
foreach($this->elements as $element) {
?>
<td class="hikashop_compare_brand_prod_column">
<?php
if(!empty($element->product_manufacturer_id)) {
$brand = $categoryClass->get($element->product_manufacturer_id);
echo $brand->category_name;
}
?>
</td>
<?php
}
?>
</td>
</tr>
<!-- EO BRAND -->
