DNS request for some hosts via VPN

[Antibiotic]

Hello, can you please get example of firewall rule for this? For example in Unbound "Domain Overrides" did some hosts to resolve via Cloudflare DNS over TLS and set to "1.1.1.1" but I want this request going via VPN gateway. Is it possible to make?

Should this correct rule, I did in floating rules:

Unbound "Network Interfaces" enabled only local interfaces + Localhost and "Outgoing Network Interfaces" enabled only Localhost
