in #woocommerce if you wanna get rid of the pay (or cancel/view) action link in orders page you can use this simple tiny piece of code that filters the action link items for an order in user account's orders page. Mind that this practice doesn't stop order pay link stop working, it merely stops them from showing in user profile page orders list.

no_order_pay_links.php

<?php

add_filter('woocommerce_my_account_my_orders_actions', 'what_is_this_pay_link_you_speak_of', 2, 10);

function what_is_this_pay_link_you_speak_of( $actions ){
    // Replace $actions['pay'] with $actions['cancel'] or $actions['view'] as needed.
    if( $actions['pay'] ){
        unset($actions['pay']);
    }
    return $actions;
}
