Have a log full of this after upgrading to 22.7.7_1... Priamry Wan is Comcast/Xfinity DHCP, Secondary WAN is Starlink DHCP
2022-05-16T09:20:37-04:00 Error dhclient unknown dhcp option value 0x52
2022-05-16T09:18:07-04:00 Notice dhclient Creating resolv.conf
EDIT: I do not have any DHCP relay enabled on OPNSense
UPDATE: Apparently this is a Starlink internal issue, I opened a support ticket with them and they responded: "Hey TRACERRX - DHCP option 82 is used for behind the scenes Starlink connection options, you can safely ignore this for now until our engineering teams can remove it. Have a good day"
