Using SD card and firmware flash on the same pins

[kiiid7]

I am preparing a schematic with the ESP32 chip now, and I want to connect an SD card to the SD_xxx pins 28-33. My problem is that I can't figure out how to separate the SD card from the flash memory which is connected to the same pins.
I want to use the SD card in 4-bit mode as standard via the ESP32's SD controller.
How is the chip supposed to distinguish between the card and the flash since they both are specified to be using exactly the same pins?

I think SD_xxx are actually slave pin designation. But HS1 is master and is also the same pins. So the answer is use HS2 instead or wait for support of SD card in parallel with main flash, but with reduced performance.
