In this letter, after briefly discussing the Hawking radiation (HR) as a quantum tunneling, we emphasize that special care must be taken when computing temperature corrections in the presence of Lorentz invariance violation (LIV), particularly by ensuring consistency between the modified dispersion relation and the gamma matrix structure used to describe fermions that are tunneling. We present a consistent implementation of such corrections in static, spherically symmetric black hole (BH) spacetimes. Our results show that introducing terms that increase/decrease the energy in the dispersion relation--originally determined by Lorentz invariance--leads to a corresponding increase/decrease in the Hawking temperature, when the dispersion relation is uniquely determined. We also determined the changes in Bekenstein-Hawking entropy for the Reissner-Nordstr\"om and Schwarzschild BHs, including corrections from LIV scenarios.
