CHUWI Hi10 X Tablet no keyboard present - Access BIOS during boot

How do I access the BIOS during boot without the keyboard being attached?
I would like to modify some BIOS settings.

You can via administrator cmd (this is the command: shutdown.exe /r /o), but you need a keyboard, because the hi10 x and xr’s uefi doesn’t support touchscreen. You can buy a cheap type C to usb A adapter and plug in an usb keyboard.
