Correct way to set alternate DNS for a single MAC/host?

I’ve just finished initial flash and config of OpenWRT and turned up AdGuard home and AdGuard DNS. So far everything except for one device on the network is behaving as expected- my Eufy camera base station. Disabling block lists and white listing via AdGuard isn’t helping it can’t communicate with whatever controls the cloud bit and switching geo location home/away from phones. I’m thinking I need to do two things:

-make a reservation for the MAC - which I did through Luci.

-use alternate DNS and pipe this host through to Google DNS (since I’m fairly certain AdGuard DNS is why the host stopped working). Since I don’t think the gui exposes setting an alternate DNS for this device, I’m going to use putty (for the first time). If I can figure out getting into the command line and getting to the host file…will this work?

config host                                          
         option name 'EufyHomeBase'                       
         option dns '1'                               
         option mac '8C:85:80:94:76:42'               
         option ip ''                    
         option tag 'altdns' 
 config tag 'altdns'                   
         list dhcp_option '6,,'

Seen ?

Ah that’s making a little sense. Thanks for the link! So for my situation:

uci set dhcp.@host[-1].name="eufyhomebase"

uci set dhcp.@host[-1].dns='1'

uci set dhcp.@host[-1].mac="8C:85:80:94:76:42"

uci set dhcp.@host[-1].ip=""

uci commit dhcp

/etc/init.d/dnsmasq restart


Make another DNSmasq instance. Which this page describes but I’m having trouble deciphering since I’ve never really done this sort of thing before. In the example it’s making a guest LAN but I don’t see where the DNS entries/IPs go
