Come on they are better than to leave us high and dry on cruise control for simply having FSD that would be LUDICROUS.
It can be done, next time you want only cruise control just enable FSD (single stalk down) and tug the steering enough to bump it out of FSD and cruise will remain enabled. Don’t touch the break until you’re ready to disable cruise control.

“When you disengage Full Self-Driving (Beta) by steering manually, Traffic-Aware Cruise Control remains active”
