How to block Bing Chat public for organization users and allowing Bing Chat Enterprise

Vimaleshwara Gajanana I tried this and it does not work in MS DNS.  You cannot create a conditional forward at the zone root level so on the production DNS this means to create a conditional forwarder for www.bing.com you must create the bing.com zone.  After doing this the prod DNS server answers bing.com queries. When I try to create a delegation at the root the "Next" box is greyed out unless I input a subdomain so I am unable to create a delegation for www.bing.com in the www.bing.com zone.  Likewise, I am unable to create a CNAME at the root of the zone either. As it was described it does not work.  Maybe you could provide the steps that worked or the work around that made it possible to delegate only www.domain.com without have a zone record for domain.com in MS DNS.
