NLBWMon IPV6 Traffic

I don't use IPV6 and never have, but I'm seeing several devices in NLBWmon showing large amounts of bandwidth consumed on IPV6 vs IPV4. I'd prefer to just see traffic from the IPV4 address. I'm not sure how IPV6 would have gigs of traffic over the IPV4, but that seems to be what's showing in NLBWMon.

Is there a specific way to disable IPV6 for this OpenWRT build? I ask because there are guides littered all over for different old builds.

Router: Netgear R7800
Firmware: hnyman OpenWrt 21.02-SNAPSHOT r16469-b59f3b08b4

My guess would be removing the LAN (or other named networks) from the config:

# grep local_network /etc/config/nlbwmon 
	list local_network '192.168.0.0/16'
	list local_network '172.16.0.0/12'
	list local_network '10.0.0.0/8'
	list local_network 'lan'
	list local_network 'guest'
