DNS Filtering on Reverse lookup zone

Hello Microsoft experts,

I'm wondering if there is a way to make DNS Filtering (based on source IP Address) available for Reverse lookup zone.

Here is the use case:

I've two appliances, both has the same IP address (192.168.1.12) and are in separate private vrf, so they can not talk each other.... Both appliances use the same Windows 2022 DNS Server (domain test.com) wich is located in a shared vrf. NAT is used between shared vrf and private vrf.

Appliance1, sub-domain example1.test.com, should request for PTR record 192.168.1.12.

Appliance2, sub-domain example2.test.com, should request for PTR record 192.168.1.12.

The problem is that DNS server respond with two records for each PTR request (appliance1.example1.test.com and appliance2.example2.test.com)

The appliance should only receive one record (the one that belong to his own subdomain), so how could we solve this use case ?

Thank you
