Is it possible to boot from SD Card?

LENOVO IDEAPAD FLEX5i
I wonder if anyone got SD card booting to work WITHOUT a SD card to USB adapter?I’ve manged to install OS on a SD card but never boot into it without a sd-card to usb adapter? It would be convient if this is possible as It would free up a usb port.
thank you to anyone who can help.:slight_smile:
