For the neutrino flux to have a measurable effect on decay rates, an enormous flux of neutrinos would be needed, not available from the sun. Consider that it takes years to gather some thousands of events from neutrinos of the sun in the neutrino experiments. A mole of matter, radioactive or not, consists of $$\sim10^{23}$$ particles and it is evident that the neutrino-matter interactions are too weak to present a field that might affect decay rates, the way that in this link electric and magnetic fields do affect slightly decay rates. The difference is that electromagnetism couples contributing with a strength of ($$1/137$$) to the cross section by each vertex, but weak interactions by $$(10^{-6})^2$$$$(10^{-6})$$ as seen in this table: The existing neutrino experiments, together with the decay rates and interactions of weak interactions, are an experimental proof that neutrinos from the sun can be ignored as far as nuclear decays go.
