(Yes, I'm stalking you, you rascally wabbit!)

Yup, it's the two pin header near the white/red leds and pwr/reset buttons, marked "eMMC en/dis"(able)... you short the two pins to disable the eMMC... or just unplug the eMMC from the board (all the jumper does is stop the eMMC clock by pulling to GND).

What I'm not clear on is why you needed to flash the SPI in order boot from eMMC... as the rock64 boot sequence is SPI -> eMMC -> SD, so if there was nothing on the SPI (i.e. as shipped from factory), it will then try the eMMC (if installed, and the disable pins not jumpered), and then the SD card...
