Does the RBR750 support DHCP option 121 ?

I am connected to the Starlink satellite system. They provide a very basic router and don't allow you to make any settings. I have my Orbi RBR750 connected to the Starlink router's aux port so that I can see Starlink's statistics but that of course creates a double NAT. It has been reported that if your router supports DHCP option 121 you can eliminate the Starlink router and still see the stats. I haven't been able to see the stats if I disconnect the Starlink router. Is there a setting I need to turn on to enable DHCP option 21 or does the Orbi not support it? Thanks for any help.
