The RK3566 boot ROM will search for a valid ID BLOCK in the following order on the support boot media:
SPI NOR flash
SPI NAND flash
SD card
eMMC
... if this fails, the boot ROM will initialize the USB0 port and wait for a connection from the Rockchip flash/boot tools.

According to the above information, SD-Card boot priority is higher than eMMC.
Assuming the above information is correct,
You should be able to do it with a simple operation of booting from an SD-Card and rewriting the target eMMC.
> upgrade eMMC image by using the USB C port ?
I can't judge whether the above is the essential condition you demand.
If your true purpose is to rewrite without removing the eMMC module,
I think you will achieve your purpose. (without using the USB-C port)
