Yes, its difficult but possible. From memory, the latches are opposite each other. So you pull toward the car on drivers side and push away from the car on the passenger side. The passenger side was much harder to reach and you have to do it by feel.
Remove the two front fixing screws from the grill. Pull the bottom of the grill outwards, it has enough flex without breaking, just enough to get your hand up to the latch on each side to operate them. Ask me how I know this works!
1999 RR 4.0, my hood release cables broke at the interior handle end. I had to remove the black plastic grille, then work my way in from underneath, finally got it released. What a pain. Then I manufactured a new handle from heavy sheet aluminum, riveted it in place, attached cables, and now it works!
