Its just unnecessary. Using both can still leave *theoretical holes* that Nintendo can use to track your console but they have not done so there is no reason to use Incognito let alone with 90DNS.
Hmm I see, why I ask, I don't really want to leave 90DNS as my only line of defense. However unlikely it is maybe someone will think it's a fun joke and hack 90DNS and then set it to allow Nintendo server connection, then everyone who happens to be connected during the time would be hosed :/
However I just thought of something else, I ordered a Powerline Wi-Fi adapter to get better coverage for Remote Play, originally I wanted it to seamlessly integrate into my home network but now I'm thinking of giving the AP a separate name. If the Powerline adapter then gets recognized as a standalone device in my home network I could simply block the AP from ever connecting outbound and have emuMMC connect to this AP only.
