SD card boot for RK3588S development board

I have youyeetooR1 sbc development module. I want to boot from SD

card.

How can I start the boot process from the SD card?

But I couldn’t find the configuration pins.

When I check the shcematic file(YYT3588S_1030/youyeetooR1

schematic.pdf), I understand that I need to change the R27 and R29

resistors to boot

I could not find R27 and R29 resistors over the board.

Can you help me.
