The bulk photovoltaic (BPV) effect that converts light into electric current is highly sensitive to the system symmetry and its electronic Bloch wave function. To create a sizable net electric current, it is necessary to break the centrosymmetry $mathcal{P}$ in its host material. While prior studies mainly focus on $mathcal{P}$-broken nonmagnetic (time reversal
