Can setting for DNS64 only resolver ?

I want to be able to test NAT64/DNS64 even if we only have an IPv4-only Internet environment.
When a native AAAA record is returned, the system waits for a timeout.

Setting 'use_dns64: true' and 'aaaa_disabled: false', then not return DNS64 records too.

general dns like this.

$ host dns.google
dns.google has address 8.8.8.8
dns.google has address 8.8.4.4
dns.google has IPv6 address 2001:4860:4860::8844
dns.google has IPv6 address 2001:4860:4860::8888

I want only DNS64 record in AAAA.
e.g.

$ host dns.google
dns.google has address 8.8.8.8
dns.google has address 8.8.4.4
dns.google has IPv6 address 64:ff9b::0808:0808
dns.google has IPv6 address 64:ff9b::0808:0404

DNS64専用リゾルバにする設定は可能か？

IPv4のみのインターネット環境で、NAT64/DNS64をテストできるようにしたい。
ネイティブのAAAAレコードが返ってくると、タイムアウト待ちになってしまう。

'use_dns64: true' と 'aaaa_disabled: false'の両方を設定すると、DNS64レコードも返さない。

一般的なDNSはこのようになる。

$ host dns.google
dns.google has address 8.8.8.8
dns.google has address 8.8.4.4
dns.google has IPv6 address 2001:4860:4860::8844
dns.google has IPv6 address 2001:4860:4860::8888

AAAAのDNS64レコードだけが欲しい。
例

$ host dns.google
dns.google has address 8.8.8.8
dns.google has address 8.8.4.4
dns.google has IPv6 address 64:ff9b::0808:0808
dns.google has IPv6 address 64:ff9b::0808:0404
