How to get bios when no keyboard

Hi…how to get in bios by upstarting when no keyboard availble for Ubookpro as probably conection line is broken …flickering access before now no connection anymore…and no black backlite keyboard availble on AliExpress or others…

BTW my not working camera started working a sudden after latest Windows updates today …wonder happened as before i tried everything …but anyway Windows Hello does say not compatible camera…

Now i am waiting to the usb- C miracle as that one usb-c stopped also many months ago same time as Camera stopped :grin:
