We introduce the first oscillation-independent astrophysical method to probe non-standard neutrino interactions (NSI) in core-collapse supernovae. Using a self-consistent treatment of NSI effects in both supernova neutrino emission simulations and flavor independent neutral-current scattering in detectors, we show that anti-correlated coincidence signatures between liquid scintillator experiments such as JUNO and dark matter detectors such as DARWIN/XLZD, ARGO, or RES-NOVA break degeneracy between NSI and flavor conversions effects. For a Galactic supernova within \lesssim1 kpc this approach enables independent probes of neutrino-quark NSI couplings in parameter space overlapping and extending beyond existing terrestrial limits. Our results establish a novel oscillation-independent avenue to test fundamental neutrino interactions in extreme astrophysical environments.
