If you can do it, it will be in the BIOS. It may not be an option in the stock BIOS and you may need to flash an unlocked one with advanced features enabled.

Hyperthreading can be disabled through the OS, and renabled subsequently by reversing the change outlined in the following proceedure.

Start > type "msconfig" > Press "enter"

Go to "Boot" tab

Click "Advanced Options"

Check "Number of processors" and set the value to 4.

Next time you restart your machine, windows will only recognize 4 cores. These 4 cores will be the physical ones, instead of 2 physical cores with 2 threads each. Therefore you will have the same experience as if you disabled hyperthreading from BIOS.

Found this on the Lenova Community page hope it helps.

This is not the case, this will be the former 2 cores 4 logical processors see below with Number of processors set to 4. 2 Cores 4 logical processors .

You need to unlock the BIOS and disable it that way. As below H/T disabled 4 cores/logical processors

But what advantage do you have if you disable HT?
