Hi,
I can deactivate the ADF receivers in the aircraft-specific options but that doesn't make them disappear on the exterior model (the two little humps on top of the fuselage roughly in the middle). They should be removed if no ADF is equipped. You can check on many photos that they are not there, like here: https://www.planespotters.net/photo/1493777/a6-eqe-emirates-boeing-777-31her
