  The circularly polarized photogalvanic effect (CPGE) is studied in chiral
Weyl semimetals with short-ranged quenched disorder. Without disorder, the
topological properties of chiral Weyl semimetals lead to the quantization of
the CPGE, which is a second-order optical response. Using a combination of
diagrammatic perturbation theory in the continuum and exact numerical
calculations via the kernel polynomial method on a lattice model we show that
disorder perturbatively destabilizes the quantization of the CPGE.
