DNS static priority, DNS fowarding?

Hello, I have this question:

Internal static DNS (e.g., nas.example.com → 10.0.0.20)

All devices use 1.1.1.3

Only my PC (10.0.0.100) uses 1.1.1.1

Using NAT and/or mangle with Ip List, I can achieve the above, but the issue is that they prioritize the static of my router 10.0.0.1 first. I've asked all the AIs and they're crazy xD.

I look forward to your comments. Best regards.
