Hi,
Well, the short answer is "it depends".
That display comes from the code:
case 'show_default':
?>
<table>
<tr>
<td rowspan="2">
<input id="<?php echo $id; ?>" type="text" value="<?php echo $current_quantity; ?>" class="hikashop_product_quantity_field" name="quantity" data-hk-qty-min="<?php echo $min_quantity; ?>" data-hk-qty-max="<?php echo $max_quantity; ?>" onchange="window.hikashop.checkQuantity(this);" />
</td>
<td>
<a class="hikashop_product_quantity_field_change_plus hikashop_product_quantity_field_change" href="#" data-hk-qty-mod="1" onclick="return window.hikashop.updateQuantity(this,'<?php echo $id; ?>');">+</a>
</td>
<td rowspan="2"><?php
echo $html;
?></td>
</tr>
<tr>
<td>
<a class="hikashop_product_quantity_field_change_minus hikashop_product_quantity_field_change" href="#" data-hk-qty-mod="-1" onclick="return window.hikashop.updateQuantity(this,'<?php echo $id; ?>');">–</a>
</td>
</tr>
</table>
<?php
break;
of the file "show_quantity" that you can edit via the menu Display>Views.
However, that code will also be used on the products listings if you display the add to cart buttons there, and on the product pages if you display the add to cart buttons there. So you need to take that into account if you modify that code.
Also, you could also do that with only CSS code that you could add in your template or in the HikaShop frontend CSS:
