WooCommerce Cart Widget

I’m trying to disable the product title and image links in the cart widget. The widget is located in the sidebar. When I open mini-cart.php and edit any of the code, the widget is unaffected. If possible, I would like to disable all WooCommerce product title and image links site-wide in order to keep users from accessing the product page. For either method, how do I go about removing the links?

The product title and image links on the shop page have been disabled using scripts below in function.php.

remove_action( 'woocommerce_before_shop_loop_item', 'woocommerce_template_loop_product_link_open', 10 );
remove_action( 'woocommerce_after_shop_loop_item', 'woocommerce_template_loop_product_link_close', 5 );

Will this be overridden if the plugin or theme is updated?
