How do I remove this garbage from my router?

I have Disney+ subscription and I have a RBR850 that has Netgear Armor on it and I can tell you that Netgear Armor does not block Disney+ so something else is causing your Disney+ to get blocked. I have also tested this on Nighthawk Models that support Netgear Armor as well as RBR50, RBR50v2 and none of them had issues running Disney+. Netgear Armor will only block access when it's running and there is an active subscription but it only blocks URLs that are known to have malware and other issues that would compromise your security. Bitdefender has a cloud service that checks for URLs that have been blacklisted and blocks access or if it detects that a website is trying to install malware on your device.  I can assure you that Disney+, Netflix, and other major streaming services are not on any blacklist that would cause Netgear Armor to block them.

Also, there is a couple of ways to disable Netgear Armor, you can use the Orbi/NH app and under Security, options disable Armor there is a KB https://kb.netgear.com/000060900/How-do-I-turn-NETGEAR-Armor-on-or-off-using-the-Nighthawk-or-Orbi-app that shows you how to do this. The other ways of disabling it include resetting your device to factory settings or letting the Netgear Armor 30-day trial expire. All these methods will disable Netgear Armor on your device. Accusing moderators of lying is not a way to disable Armor.
