Presuming there isn’t some unknown, unannounced, non-commercial tech provided to DoD or USSS by NSA or the like?
There isn't, as far as I'm aware, and I think I would have heard if there were. There are EM disruptor solutions that can remotely disable UAVs, but those are for use in war zones or perhaps extreme national security situations. I cannot imagine them being deployed at an event like this on US soil - especially when there were almost certainly other aerial assets in the area belonging to LE and the media.
