Boom’s @Starlink implementation for XB-1 program cost 0% fuel because our install was completely “conformal”—no change to the airplane’s aerodynamics at all. Overture will be the same: Antenna spaces built into the airframe so no bumps and no drag.

NB: the antenna was actually on a T-38 flying in formation not XB-1 itself—because we wanted a close up live view of XB-1 from outside the airplane. But the same conformal install would have worked on XB-1.
