Sure, you can achieve it by editing this file:
/templates/ja_megastore/html/com_virtuemart/sublayouts/products.php
And add this snippet of code to render the details button:
<div class="show-desc">
<div class="vm-details-button">
<?php
$link = empty($product->link)? $product->canonical:$product->link;
echo JHtml::link($link.$ItemidStr,vmText::_ ( 'COM_VIRTUEMART_PRODUCT_DETAILS' ), array ('title' => $product->product_name, 'class' => 'product-details' ) );
//echo JHtml::link ( JRoute::_ ( 'index.php?option=com_virtuemart&view=productdetails&virtuemart_product_id=' . $product->virtuemart_product_id . '&virtuemart_category_id=' . $product->virtuemart_category_id , FALSE), vmText::_ ( 'COM_VIRTUEMART_PRODUCT_DETAILS' ), array ('title' => $product->product_name, 'class' => 'product-details' ) );
?>
</div>
</div>
you can add to the place you wish, for example, underneath the description: https://prnt.sc/tmelxv
