  This short note presents an extension of the hybrid, model-adaptation method
introduced in [T.~Laidin, \textit{arXiv 2202.03696}, 2022] for linear
collisional kinetic equations in a diffusive scaling to the nonlinear
mean-field Vlasov-Poisson-BGK model. The aim of the approach is to reduce the
computational cost by taking advantage of the lower dimensionality of the
asymptotic model while reducing the overall error. It relies on two criteria
motivated by a perturbative approach to obtain a dynamic domain adaptation. The
performance of the method and the conservation of mass are illustrated through
numerical examples.
