Remove CNAME records from response for specific domains

### The problem

I hope that certain specific domain names will respond only with IPv4 records and that the CNAME record will be removed,when I configure a specific domain name to return only 'A' records in the [Filters->dns_rewrites] function page, and a dual-stack client queries this domain name, if the queried domain name resolves to a CNAME, the client will continue to query the IPv6 records of the CNAME. This leads to the configuration not taking effect.

More specific scenarios：
While accessing chatgpt or bard or copilot, I have to disable ipv6 to access them due to geo access restrictions set by these sites and my proxy only supports ipv4. However, the domain name `chat.openai.com` is currently resolved to the address `chat.openai.com.cdn.cloudflare.net`.I can only achieve my goal by configuring both `chat.openai.com` and `chat.openai.com.cdn.cloudflare.net` in the [Filters->dns_rewrites] page to retain only the A record. But suppose one day `chat.openai.com` changes its CNAME domain, then my configuration will become invalid.

### Proposed solution

certain specific domain names will respond only with IPv4 records and that the CNAME record will be removed.
