I believe the bios locks some features like the ones you mentioned, updating the bios shouldn't fixed that since it is a feature from the chassis
Yep, that's correct. Laptop BIOS's arent the same as desktop and are fairly locked down with all settings defaulted such as virtualisation is enabled, hyperthreading enabled, turbo boost etc etc.
Just to point out that even though this is true, as with everything else there is always a way around it in this case being the modded bios, which under no circunstances should you use unless you are 99% they are legit and useful and to remember that doing this will void your warranty
