How to block extremist and terrorist content using NextDNS?

As the title suggests, are there filters available that can block this type of content?

In the UK, educational institutions are legally required to protect children by blocking access to inappropriate content - extremist and terrorist content is a specific category and rightly so.

With this in mind, I've searched extensively, but I can't find any filters that provide this kind of protection. None of the readily available lists seem to mention that they block such content either.

Or is this something that NextDNS might be planning to develop in the future, similar to how it can block child sexual abuse material?
