Payment Method is listed on checkout even when Enable config set to No

[mozok]

I have issue with multistore Magento 2.4.2-p1 setup. I need Payment Method to be available only for one website (now we have 3 websites in one M2 setup). But even so in admin configuration PayU and PayU Card set to "Enable - No" it still displayed on checkout page.

Steps to reproduce:

1. Configure 2 Websites in Magento 2.4.* - website_1 and website_2
2. Install module via composer
3. In admin configuration set configs for PayU and PayU card for website_1: Enable Plugin - No. For website_2: Enable Plugin - Yes.

Expected result:

• On website_1 checkout PayU is not available in payment methods list.
• On website_2 checkout PayU is available in payment methods list.

Actual result:
PayU is available in payment method list for both websites.

Research:
This is caused by config active in etc/config.xml. During PayUPaymentGatewayFacade initialization only this config is checked.

Suggested solution:
Add validatorPool to payment facades as shown in documentation https://devdocs.magento.com/guides/v2.4/payments-integrations/base-integration/facade-configuration.html.
For example facade KPVirtual in vendor/klarna/module-kp/etc/di.xml and it's availability validator - \Klarna\Kp\Gateway\Validator\SessionValidator
