Simultaneously use microsd and emmc on jetson xavier agx + micro sd card slot not working?


I’ve seen this question

for Jetson Nano where kayccc said

“The micro SD and emmc images are different, they can’t be used simultaneously.”

But I’m curious if it is possible to use a 32GB micro sd card in conjunction with the 32GB emmc to increase memory to 64GB on Jetson Xavier AGX? Can I get steps on how to use the 32GB micro sd card? Or can I only boot from one or the other?

Actually, I cannot seem to get the micro sd card to read in the slot that is right next to the GPIO pins (I have the development agx xavier board).
