Can you share your config? I am able to browse the site that are using Cloudflare. Everything else not working.Yes and no. There doesn't seem to be any official way, but it uses Wireguard, so if you can get your hands on the right config, it should work with RouterOS v7 (currently it's only beta).
I tried quick test with https://github.com/ViRb3/wgcf, which is some tool that can register account and get config, and when applied to RouterOS, it works. Well, it worked for about five minutes when I was testing it, but I have no idea if it should last forever or if it will have to be updated in future. Neither I know anything about their terms of use or anything like that.
Let's say that at first sight it's not completely hopeless.
