**Figure 1.**Variation as a function of the zenith angle on the expected KM3NeT number of neutrino events in 10 years of observation with respect to the standard oscillation scenario for different values of VEP parameters. Left (right) panel corresponds to the case of direct (inverse) ordering of VEP parameters. The effect of VEP is a deficit of vertical upgoing neutrinos. All the uncertainties affecting the expected events are here neglected.

**Figure 2.**KM3NeT-forecasted 10-year constraints at 90% CL on the VEP parameters for direct ordering (${\gamma}_{21}\times {\gamma}_{31}>0$) and inverse ordering (${\gamma}_{21}\times {\gamma}_{31}<0$). The bands cover all the Monte Carlo simulations of mock data samples. The blueish and yellow colors correspond to a systematic error of 0.01 and 0.04 in the data generation, respectively. The solid and dashed white lines are the mean constrains for the two values of the systematic error. The thin black lines show the IceCube limits obtained by means of a similar analysis [51].
