We show that charged-current accelerator (anti)neutrino interactions on $^{40}$Ar, producing $\\Lambda$ and $\\Sigma$ inside the nucleus, can constrain these potentials. At SBND and DUNE energies, the trapped-$\\Lambda$ fraction and escaping-hyperon momenta vary monotonically with $U_\\Lambda$ and $U_\\Sigma$, with a kaon-vetoed FSI-$\\Sigma^+$ tag adding sensitivity.
