With the help of reddit, I managed to find a way to bypass the pihole straight to google 8.8.8.8 , It is set up by mac address.

Find the mac address and place this in your /etc/dnsmasq.d/ directory 394.

cd /etc/dnsmasq.d/

wget https://raw.githubusercontent.com/deathbybandaid/piadvanced/master/piholetweaks/dnsmasqtweaks/04-bypass.conf

nano 04-bypass.conf
(replace mac address)

dnsmasq --test
(tests the configuration)

sudo service dnsmasq restart
Or
sudo reboot

It would be awesome to do something like this via the webui!
