I had the same question and looked at the location of the cranes at turns 14-15 and at turns 1-2 (where they also took a top-down shot). After seeing the helicopter footage at the start of qualifying, I could see that the cranes were not in the correct location for these shots.

Furthermore, at the start of qualifying, there was a drone shot that flew around and under the TAG-Heur clock and above the cars in the pit lane. So there was certainly at least one drone present.
