If you also want a functional SD_DETECT_PIN then you'll need to also move the following pin:
used to go to P0.27 to J8-5
if you decide to use a different pin then the pins_MKS_SBASE.h file will need to be modified.

/**
* P0.27 is on EXP2 and the on-board SD card's socket. That means it can't be
* used as the SD_DETECT for the LCD's SD card.
*
* The best solution is to use the custom cable to connect the LCD's SD_DETECT
* to a pin NOT on EXP2.
*
* If you can't find a pin to use for the LCD's SD_DETECT then comment out
* SD_DETECT_PIN entirely and remove that wire from the the custom cable.
