Well.. kinda? Makes me wonder about just dropping munitions on the entrance, or even just using conventional explosives.

And yes, I don't know the skill set to validate the thought. However, I have seen beaver dams cleared with dynamite, and there's a wide level of explosives which can be dropped or deployed on foot...

(People saying it would be violent, well sure, but so is dropping bunker busters...)

Beaver dams are not several dozen tons of dirt. You are not going to C4 through several tons of loose dirt.
