Interface does not exist warning in "Pi-hole diagnosis" tab

In my setup, 4.5.9-1, I have several interfaces (eth1,eth2, eth3,eth4) that are bonded to form bond1. When starting the pi-hole rock-on I see this error message under Pi-hole diagnosis

“interface eth0 does not currently exist”

It looks like there is a setupVars.conf that is setting this.

INSTALL_WEB_INTERFACE=true
WEBPASSWORD=d000c93ef1811fbbfb8ec407ed37e72532f3d57a0e18cf71cbf39edf51bf36a2
PIHOLE_DNS_1=8.8.8.8
PIHOLE_DNS_2=8.8.4.4
PIHOLE_INTERFACE=eth0
QUERY_LOGGING=true
BLOCKING_ENABLED=true
TEMPERATUREUNIT=C

I have tried changing it to bond1, but every time I restart the pi-hole rock-on it gets set back to eth0

Is there a supported way to update this to use my bond1 interface?
