@manawyrm I don't know where else the 5V rails go on the board since I don't have the rest of the schematic, but based on how they've named the power nets it's a pretty reasonable guess that the only other usage of the 5V rail is for the USB ports, and since you're disabling those anyway you should be fine. the 5V_CORE is almost certainly a filtered power domain used only for the RT8088.
