Hello,

What are the SDIO connection pins (CMD, CLK, DATA0, DATA1, DATA2, DATA3)
of the ESP32-S3 module?

The example at https://github.com/espressif/esp-idf/tr ... card/sdmmc shows you how to set SDIO the pins. Also on ESP32-S3, any available I/Os which is not used for other purposes can be used for SDMMC peripheral. The driver will use the GPIO matrix to route the I/Os to the peripheral signals. Please refer above README.md for the details.
