Resucitar VI8 CWI519

Hi there:
I have a chuwi VI8 CWI519 tablet and it only goes into BIOS, but not EFI. Could someone help me configure it to start from USB, since I have tried everything and it only stays on the initial screen with the chuwi image, and it does not advance. I also need the drivers, would that be possible?

Thank you.
