Power a J1010 or J1020 through the J10 header

In order to add UPS functionality to the reComputer J1010, I would like to have the possibility to power it through the 40-Pin Expansion Header (J10). Is it possible to reconfigure the supply to do so, or is it only possible through J1 (USB 2.0 Type C power in only)

There it is a possibility to power the board trough J10 connector using pins 2 and 4 (5v Power)? Need to do any setting?
The original board from Nvidia is working but this one doesn’t work.

I encountered the same issue. You have to slightly modify the board by shorting a protection diode to get the same behavior as on the original Nvidia demo board.
