If you pull the frunk liner, there are torx screws across the bottom of the radiator cover. You could see if loosening those buys you anything. The radiator cover side mounting as well as the frunk hinges have screws thru the fender aprons, and require wheel liner removal and maybe headlight removal, to gain access. The radiator cover itself is made of kinda thin metal, and can be gently persuaded, if your issue is minimal, and all else is in good alignment. You can use a sheet of paper, to slide between the frunk and radiator cover, to find tight spots, and ensure no contact. Good luck.
