How to disable IPN

Hi everyone,

I was wondering if there is a way to disable the Instant Payment Notification (IPN) URL of the paypal donation button, so that Paypal can send IPNs to another site. Despite setting up our desired IPN address in PayPal, it is still sending donation notifications to the URL https://example.org/wp-admin/admin-post.php?action=add_wpedon_button_ipn.
