@Cardinal95 Not familiar but sounds like a good option:

@Cardinal95 Adguard DNS blocks adult content along with ads. You just have to set it as your Primary and Secondary DNS in the Deco app and adult content won't load. Apologies for the poor photo editing on my phone lol. 

On the bottom right of the app you'll see More, select that and you'll see options, look for Internet Connection. From there you'll see your IPv4 and IPv6 settings, you want to Manually set your DNS Address for each using the 4 above settings.

Fair warning, some video services like Paramount+ won't load with Adblocking, suggesting they're getting more than we'd imagine from them. Best of luck!
