Electrical work (accessories) on hybrid. Disconnecting 12v battery?

[FinnTaco]

Getting ready to install a TRD pro grill and worried about disconnecting the wiring harnesses and it throwing codes. Has anyone removed the grill already? Do you need to get under the seat to disconnect the 12v battery? Appreciate any advice.

I did the heritage grille swap and did not disconnect battery on my ltd hybrid and no codes or issues at all.
