I'm trying to follow the "Require commercial data protection in Copilot" in the following article, which says that I can prevent the use of Copilot without commercial data protection: Update your DNS configuration by setting the DNS entry for www.bing.com to be a CNAME for nochat.bing.com
I am unsure how to do this with Microsoft DNS. I can try creating a primary forward looking zone just for www.bing.com, but Microsoft DNS does not allow to create a CNAME record for what looks like an apex domain, plus it stops regular bing searches from working at all.
Any ideas on how to do this recommendation?
