It turns out SDMMC3 on the Jetson Nano module is wired to respective pins of
the carrier's M.2 Key E socket. However, it is not enabled. I see no reason
why. This block is functional and has a fixed 1.8 V I/O supply. Perfect for
SDIO cards nowdays. I think it would make sense to enable this feature. PCIe
could be used for something else.

Kind regards,
Tamas
