Laptops are not my “strongest” area… in fact i kind “hate” laptop systems…wast of money especially for gamers, good for work only.
Setting a value in those variables using RU is a temporary solution for dumping with unlocked values, as soon as the system powers down/reboot the default are restored.
So most cases what users do is to flash that unlocked dump to the SPI IC, when possible with FPT tool or SPI programmer, other solution is to edit the FD by HEX editor and flashing with SPI programmer or FIT tool on ME region if FPT tool can write to the ME region only.
All these are RISK operations that can lead to a death system,
cant help more on this, good luck.
