I was wondering if there were any plans to provide us the ability to completely disable the built in DNS with Edge. I understand that you can disable the DNS however this does not really resolve all the issues.
I work at an organization that has it's intranet page as the default home page on all devices, on the internal DNS server we have it pointing to the intranet server obviously. However when users go home the external DNS server points that same URL to the external site page instead. We have the TTL on that record set to 30 seconds however when users come back in the site still points them to the external site. Running a ipconfig / flushdns does nothing. I found out that if you clear the browser cache it then resolves properly again. I am not entirely sure what is causing this but I'd really appreciate a fix for this or a way to manage this functionality.

in Edge settings, set DNS to "Use current service provider"
can be configed via group policy:
set that to "Off"
The "off" mode will disable DNS-over-HTTPS.
also disable this:
"This policy controls which software stack is used to communicate with the DNS server: the operating system DNS client, or Microsoft Edge's built-in DNS client. This policy does not affect which DNS servers are used: if, for example, the operating system is configured to use an enterprise DNS server, that same server would be used by the built-in DNS client. It also does not control if DNS-over-HTTPS is used; Microsoft Edge always uses the built-in resolver for DNS-over-HTTPS requests. Please see the DnsOverHttpsMode policy for information on controlling DNS-over-HTTPS."
"If you enable this policy, the built-in DNS client is used, if it's available.
If you disable this policy, the built-in DNS client is only used when DNS-over-HTTPS is in use.
If you don't configure this policy, the built-in DNS client is enabled by default."
by the way, this part is a bit confusing: "However when users go home the external DNS server points that same URL to the external site page instead. "
you only have a homepage URL which is a website hosted internally, then what is the external site page?

I've tested the configuration and it does not seem to work still.
So to give you more clues as to what's going on, even after flushing the DNS cache the website still directs to the external web page while on site unless I clear Edge cache. One I clear Edge cache it will now begin to resolve correctly again. Do you know if there is something that caches webpages for faster loading in Edge chromium? If so I think that would be the culprit. I will also do my own research into the matter and respond back if I find the solution.
Well yes there is "Preload pages for faster browsing and searching" option in settings
Another workaround for this, you can use this option here:
just check the box that clears browser cache every time Edge is closed.
and are you sure it's not the cookies and only cached data like images, files etc.? because if it was cookies you could add only that domain to clear on exit.
