Is there a way to override this behavior?

Here is an ugly way: you could filter the incoming DNS answer packet with iptables, send it to a userspace program (NFQUEUE target) which will then counterfeit it to change the TTL.

I would not recommend this even if it were possible. One scenario: When servers are brought down for maintenance, they are removed from DNS. The admins will then wait for the DNS records to expire before shutting the server itself down. By overriding the TTL you'll be sending traffic to a server that could be shut down.
