Cloudflare can do this. Even for domains you don't buy there. You can use a free account. Their Security Center scans warn you of this and other configuration issues you may not consider.

Edit: Sorry, you did say "one click way." I meant the warning of these things can be done on a free account, but the actions taken can only be done on a domain bought through CF. I don't think there can be a "one click way" for this type of change because a misconfiguration can have a huge impact on your business if you're not careful.
