update variations via php

This plugin looks perfect for my use case. I am abandoning some (premium) plugins that does not offer the functionality that this does. So thanks a lot.

I want to find out, is there a way that I can update min quantity for product variations via php? Something like update_post_meta perhaps? The reason why I want to do this, is because I have the data in another plugin, but want to transfer it over to yours without manually changing each variation. So I’m doing something like: `

$args = array(
        'post_type'      => 'product',
        'posts_per_page' => -1,
    );
		$loop = new WP_Query( $args );

     while ( $loop->have_posts() ) : $loop->the_post();
        global $product;	 
	$min_value = get_post_meta(get_the_id(), 'old_plugin_meta_for_min', true );

	if ($min_value) {
    //	update_post_meta( get_the_id(), 'berocket_min_quantity', $min_value );
			
		}
     endwhile;

     wp_reset_query();

This works 100% fine for simple products, but is this possible with variations?
