Shuttle LX1 (XEM6006) 12V to FMC

I need to apply 12V DC to my FMC peripheral board. The shuttle LX1 manual says that this can be done via test point TP10. However, this point is connected to the 5V circular power plug.

The manual mentions that R23 could be populated so that the OK board can be powered (5V) via the FMC peripheral through the 12V FMC pins. R23 came populated on my board!?

If I depopulate R23 can I apply +12V to TP10 in order to power my peripheral board?
