In order to do this

We have to inject \Magento\Payment\Gateway\Config\ConfigFactory in ConfigProvider class

const CODE = 'code_gateway';
private $config;
function __construct(
   \Magento\Payment\Gateway\Config\ConfigFactory $configFactory
) {
   $this->config = $configFactory->create(self::CODE);

    public function getConfig()
        return [
            'payment' => [
                self::CODE => [
                    'gateway_ID' => $this->config->getValue('gateway_ID')

Now in gateway_renderer.js

gatewayID: function () {
   return console.log(window.checkoutConfig.payment.code_gateway.gateway_ID);

on template.html

<button class="action primary checkout"
     click: gatewayID,
     attr: {title: $t('Place Order')}
    <span data-bind="i18n: 'Place Order'"></span>
