To jam, presumably you need to know precisely where the receivers are.

You need to know where you don't want functioning receivers.

Can a neutrino detector estimate the direction from which a neutrino arrived?
I'm wondering if that could help discriminate signal vs. jamming.
Some neutrino detectors can estimate direction, see
https://en.wikipedia.org/wiki/IceCube_Neutrino_Observatory
which should be able to spot a supernova in our galaxy easily.
Signals aren't jammed by being blocked but overpowered. If you want to disrupt someone's neutrino comms, you don't start building lead walls. You flood their volume with neutrino noise. (I don't know how feasible that is to continuously do over a large volume.)
