Is there a way to override DNS settings OPNsense gets from WAN dhcp (ISP)? I don't want the device using their DNS nameservers, etc.
I noticed resolv.conf has ISP nameservers.

In "System: Settings: General", uncheck "Allow DNS server list to be overridden by DHCP/PPP on WAN" and OPNsense won't use the ISP DNS any longer.
