Windows 10: Unable to change DNS Encryption for Alternate IPv6 DNS

I manually set my DNS settings SETTINGS > NETWORK & INTERNET > ETHERNET > EDIT DNS SETTINGS. When I try to change my DNS Encryption for the Alternate IPv6, it is grayed out and "Unencrypted Only" is the default. After saving the settings, the manual changes reflect what I could enter. The Alternate DNS encryption listing shows Unencrypted, which I don't want. From everything I could find, this setting can be changed and addresses are correct. How to I enable this to be changed?

DNS problems with router

A couple suggestions I have for you:

Update the firmware on the router. Maybe it's getting into a badstate, and a firmware update might fix it. Or if you're comfortable with it, install a custom firmware like dd-wrt. Just make sure its supported on your router first.

Change your DNS to: 8.8.8.8, 4.2.2.1. Might help.

If none of these work, maybe statically set your DNS on your PS3/PC to the IPs you listed, taking the router out of the lookup procedure.

Last option, is look for a new router.

 

IPv6 DNS server addresss

I have spoken with my ISP and the modem OEM. One says because it is not leased equipment they cannot make the changes. The other says that because I do not have a router or Wi-Fi, they cannot make the changes. So I spoke with the laptop OEM and they say
maybe, maybe not.

It was implied by one of the three that maybe OS support could help.

So I'm asking you. How do I add an IPv6 DNS address to my **** SB 6121 Ethernet modem?

Below is the warning and as more URLs began to use a DNS server on IPv6, the problem will get worse

Errors when setting Alternate DNS server

I do not have IPv6 connectivity at this time, which is why it is off in my configuration. That should not effect the alternate dns server. And in fact I can save the settings as long as I don't put in the alternate.
