You can enter via Windows/settings/update/restore/Advanced/reboot/troubleshooting/UEFI and you will enter BIOS but that`s it, without keyboard you cant navigate menu but you will be able to see your version;Â Â and to exit you need to press both volume buton and power buton simultaneously and hold them until tablet restarts or just volume buttons – i dont remember- try it. Otherwise attach keyboard trough otg cable and you should be fine.
