How to Connect ESP32- D0WDR2 – V3 with External Flash and Emmc?

Hi,
ESP32- D0WDR2- V3 has a 2 MB bedded PSRAM but only 448KB internal flash. Is it possible to connect an external flash( for law and data) and an eMMC( storage only) and make all of three( PSRAM external flash eMMC) work together?
When I read runner 18 of ESP32 datasheet, above Table 2, it states” Table 2 lists the pin- to- pin mapping between the chip and the bedded flash/ PSRAM. The chip pins listed then aren’t recommended for other operation.” This seems to indicate that the affiliated pins(SD_DATA0- 3,SD_CLK, GPIO16) are used by bedded PSRAM and can not be connected to external flash or emmc. Could anyone confirm if that’s the case? But without using those pins, an external flash won’t be suitable to memory counterplotted into cpu memory space. Am I right?
Thanks for your help.

    You could use those pins enthralled by bedded PSRAM to connect an external flash( for code and data), but you should use another free GPIO to connect an eMMC( for storage ).
