Hello,

I have double-checked, Unfortunately, it is not possible to separate Add to Cart and Swatches. It would destroy the Add to cart functionality.

We can suggest the solution: custom code which you need to add to functions.php of the child theme:

add_action( 'woocommerce_after_variations_table', function () {
	echo do_shortcode( 'SHORTCODE_NAME');
});

You need to replace 'SHORTCODE_NAME' with the name of the shortcode calling the template of the single product.

If you have any questions please feel free to contact us.

Best Regards
