Any client using Pi-hole will have the queries logged the same as any other client, dependent on your privacy and logging settings. If you log one, you log them all.
Since you appear to not want that client to have any blocking, you have a few options.
-
Manually change the DNS assignment on that device to a DNS other than Pi-hole. You won't see any activity from that device in Pi-hole.
-
If Pi-hole is your DHCP server, you can use a dnsmasq configuration to assign that client (by MAC ID) a DNS server other than Pi-hole. This achieves the same as (1) above, but you don't have to manually configure the client.
