Hide shipping address on WooCommerce orders based on specific shipping methods

I have two flat rates (flat rate:1 and flat rate:2) I would like to hide the “Shipping Address” in WooCommerce Thank you page when “Flat rate:2” shipping method is chosen.

Trying to use something based on WooCommerce – Hide shipping address when local pickup is chosen on thankyou page, but I’m stuck.

Can anyone give a some tips how to achieve this?

You can use this simple code snippet, to hide shipping address from orders based on specific defined shipping methods:

add_filter( 'woocommerce_order_needs_shipping_address', 'filter_order_needs_shipping_address', 10,  );
function change_order_received_page_title_based_on_order_status( $needs_address, $hide, $order ) {
    // Here set your shipping method instance Ids
    $targeted_instances_ids = array( 1, 2 ); 
    
    // Loop through "shipping" order items
    foreach ( $order->get_items('shipping') as $item ) {
        if( in_array( $item->get_instance_id(), $targeted_instances_ids ) ) {
            return false;
        }
    }
    return $needs_address;
}

Code goes in functions.php file of the active child theme (or active theme). Tested and works.

Note: The shipping instance ID is the number after : in a shipping method rates ID.
So for example for flat rate:2, the shipping instance Id is 2.
