The parts catalog says '12 R51's here in the 'States didn't come with a xenon option, so I assume you're either overseas or it's a transplant. I will say, I don't know of any Nissan model where the OE xenons can't be downgraded to OE halogens with a little rewiring. For vehicles with xenon low beams and halogen high beams, the power connectors into the ballasts simply need to be clipped and replaced with H11 connectors from the parts store, then directly connected to the low beam bulbs. Vehicles with high-low xenons are a little more complicated because the wires and fuses for the aiming solenoids are too small to drive the high-beam elements. So you need a pair of 15A inline fuses and a pair of "Bosch Box" relays from the parts store. For each headlight, connect the existing ballast power and ground wires respectively to the low-beam and ground wires on the 9004 connector, then connect the 9004 high-beam wire through a relay as follows (pin numbers will be stamped or molded on the relay):
30 - 9004 high beam wire
85 - existing high-beam solenoid wire
86 - ground
87 - inline fuse from battery+
87a - unused
