I want to enable captcha on guest checkout in Magento 2.3.1. I am using the one-step checkout.
I know that it is a simple question and you can follow this nice article to do that: https://www.mageplaza.com/kb/how-to-enable-customer-login-register-captcha-magento-2.html
However, I believe that there is something wrong with my Magento installation and it is not showing me "Check out as guest" option in form section inside Captcha.
Can I enable "Check out as guest" option manually using the command line or terminal or FTP?
