How to disable emmc

#1

Hi
I’d like my rockpi X to boot on the usb3 rather than emmc(on witch i ve an other OS) without going each time on the bios to overide and select the usb3(ssd) to boot on.
I ve search on bios with no luck for now…
Is there a way to disable the emmc somewhere??

If save boot priority doesn’t work for you, try to attach the RTC battery…
