To remove from all viewcontrollers in a navigation controller stack:

subclass UINavigationController and add this:

override func show(_ vc: UIViewController, sender: Any?) {
    setEmptyBackButton(vc)
    super.show(vc, sender: sender)
}

override func pushViewController(_ viewController: UIViewController, animated: Bool) {
    setEmptyBackButton(viewController)
    super.pushViewController(viewController, animated: animated)
}

func setEmptyBackButton(_ viewController: UIViewController) {
    viewController.navigationItem.backBarButtonItem =
        UIBarButtonItem(title: "", style: .plain, target: nil, action: nil)
}
