Cloudflare DNS now have 2 more varients: The one that does no filter, filter only malware, filter malware and porn
I suggest adding those into the default DNS list, like Quad9 having 3 varients.
Cloudflare No Filter: 1.1.1.1, 1.0.0.1
Cloudflare Maltware Filter: 1.1.1.2, 1.0.0.2
Cloudflare Maltere and Porn: 1.1.1.3, 1.0.0.3
