Change DNS Server for 1 device

I have my gold+ set up using DNS over HTTP to cloudflare which is what I want for all but 1 device, my smart TV which I want to use SmartDNSProxy for

It's connected via Wifi and I want other wifi clients to go via the normal DoH

I'd rather not run all traffic through that, but only the TV which seems like something that Firewalla should be capable of but I can't seem to figure it how to set it up
