The prodedure fro the Pi Pad 5 which is a similar device is shown here:

How to install Raspberry Pi OS on the Raspberry Pi Pad 5?

Instruction from the above link:

• Now we need to flash Raspberry Pi OS on to a micro-SD card (for non-eMMC version) or to eMMC storage (for eMMC version), so that it can run on the Raspberry Pi Compute Module 4.
• Flash to Micro-SD Card (CM4 Non-eMMC Version)
• If you have a Compute Module 4 without eMMC, then you need to insert a micro-SD and flash the Raspberry Pi OS.
• Follow the steps below according to your operating system.
• Step 1. Insert a micro-SD card to the computer using a micro-SD card reader connected to the computer, or by using a built-in card reader on a laptop
• Step 2. Download Raspberry Pi Imager software by visiting this link
• Note: You can choose to download for either Windows, Mac or Ubuntu
• Step 3. Open Raspberry Pi Imager software
• Step 4. Click CHOOSE OS and select the latest version of the Raspberry Pi OS (32-bit)
• Step 5. Click CHOOSE STORAGE and select the connected micro-SD card
• Step 6. Finally, click WRITE
• Please wait a few minutes until the flashing process is complete.

This is the same procedure as for instance with a Pi 4 which is easier as for a Pi Pad 5. Eventually we receive support in the Seeedstudio forum how to do this:
