How to disable opencart payment method selection warning?

Question

opencart

You can remove the message in the cart You must choose a payment method! in opencart 2.3?
I hid the methods themselves in the display. In the admin panel, I left only one method enabled - Payment on delivery.
But in the payment_method.php controller, there is a check for the existence of a payment method

$results = $this->model_extension_extension->getExtensions('payment');

      $recurring = $this->cart->hasRecurringProducts();

      foreach ($results as $result) {
        if ($this->config->get($result['code'] . '_status')) {
          $this->load->model('extension/payment/' . $result['code']);

          $method = $this->{'model_extension_payment_' . $result['code']}->getMethod($this->session->data['payment_address'], $total);
                    
          if ($method) {
            if ($recurring) {
              if (property_exists($this->{'model_extension_payment_' . $result['code']}, 'recurringPayments') && $this->{'model_extension_payment_' . $result['code']}->recurringPayments()) {
                $method_data[$result['code']] = $method;
              }
            } else {
              $method_data[$result['code']] = $method;
            }
          }
        }
      }

      $sort_order = array();

      foreach ($method_data as $key => $value) {
        $sort_order[$key] = $value['sort_order'];
      }

      array_multisort($sort_order, SORT_ASC, $method_data);

      $this->session->data['payment_methods'] = $method_data;

  if (empty($this->session->data['payment_methods'])) {
      $data['error_warning'] = sprintf($this->language->get('error_no_payment'), $this->url->link('information/contact'));
    } else {
      $data['error_warning'] = '';
    }

    if (isset($this->session->data['payment_methods'])) {
      $data['payment_methods'] = $this->session->data['payment_methods'];
    } else {
      $data['payment_methods'] = array();
    }

    if (isset($this->session->data['payment_method']['code'])) {
      $data['code'] = $this->session->data['payment_method']['code'];
    } else {
      $data['code'] = '';
    }

As I understand it, the session is recorded. Can I substitute something there so that it takes this value? And in what form should it be?
