Using Ultralow on PFSENSE Resolver

Is there a way to redirect PFSENSE resolver to the ultralow servers. The current setup using anycast takes me to DXB and it has 165ms latency

server:
  forward-zone:
    name: "."
    forward-tls-upstream: yes
    forward-addr: 45.90.28.0#<my-id>.dns1.nextdns.io
    forward-addr: 45.90.30.0#<my-id>.dns2.nextdns.io

If I put the IP of ultralow directly, the resolution stops functioning
