Looking at the daughter card's schematics, there are several un-used pins on the cable, 7, 8, 33, & 34. Just enough for another SPI device, (flash or otherwise). I've not yet checked the main board, but the RK3399 has 6 SPI interfaces. SPI 1 is already used for the bootable flash device. Some others have the pins re-purposed to something else. But their might be one of the 6 that is un-used at present.
Perhaps a hardware moder version of the daughter board can use this as an interface.
