How to change the link of product menu from wordpress admin panel

Question

You can modify the admin navigation using the $menu global var. The following will accomplish what you’re after

add_action( 'admin_menu', 'my_plugin_edit_admin_menu');
function my_plugin_edit_admin_menu() {
    global $menu, $submenu;
    foreach ($menu as $menuKey => $menuItem)
        if ($menuItem[0] == 'Products')
            $menu[$menuKey][2] = 'https://google.com/'; // wtv link you want

    // UPDATE:
    // remove the sub menu as well (note the GLOBAL var define above)
    $submenu['edit.php?post_type=product'] = ''; 
    unset($submenu['edit.php?post_type=product']);
}
