The lemans EVK board supports either eMMC or SD-card, but only one can
be active at a time.

Move the SDHC node for SD card into a dedicated device tree overlay.
This decoupling allows the storage medium to be selected dynamically by
applying the appropriate overlay for either SD card or eMMC support.

What is wrong the SD being a default one?
