The DUNE physics program primarily focuses on signals in the GeV energy range. In recent years, DUNE's potential as a low-energy experiment has been explored expecting some sensitivity to signals as low as 5-10 MeV such as supernova burst and solar neutrinos. In this presentation I discuss the requirements and modifications that could extend DUNE's sensitivity to energies as low as 2MeV which would enhance DUNE's physics program and could expand it to enable searches for neutrino-less double-beta decay in xenon-doped liquid argon. I will present the modifications we propose with corresponding sensitivity estimates for measurements of the absolute neutrino mass scale (mββ) beyond the sensitivities expected from current and next generation neutrino-less double beta decay experiments. I will describe the rich and diverse R&D program that this research avenue would open for DUNE in the coming years.
