I would try to load newest vbios through Clover, or replace one in your device Firmware. There is a info about loading vbios through Clover in here: https://clover-wiki.zetam.org/configuration/graphics#graphics_loadvbios and for updating vbios in Firmware try this guide: https://www.win-raid.com/t154f16-Tool-Guide-News-quot-UEFI-BIOS-Updater-quot-UBU.html
