Micro SDCard of Mini Router with CM4 for reading data

Dual Gigabit Ethernet Carrier Board for RPi CM4 with 4GB RAM, 32GB eMMC and PC/ABS Case with Aluminum Heatsink - Seeed Studio

Can I use Micro SDCard slot to plug any SDCard memory and develop the software to read data on SDCard?

Have anyone know about this, After flash OS to eMMC then I would like to use SDCard slot to plug any SDCard then develop software to read binary data on SDCard.

Can I do it with this product https://www.seeedstudio.com/Dual-GbE-Carrier-Board-with-4GB-RAM-32GB-eMMC-RPi-CM4-Case-p-5029.html ?
