Thank you for contacting the Intel Communities.
While using OEM systems like yours, the recommendation is to download and install the drivers from your computer's manufacturer website.
This is to avoid loosing any special features or settings while using the generic drivers from Intel.
While uninstalling the drivers from your computer, please make sure you select "Delete the driver software for this device".
Additionally,you could try with some third party software that uninstalls software from your computer, an example would be ccleaner*, I personally use this software for different tasks and it works fine. CCleaner - PC Optimization and Cleaning - Free Download
Please note this is just a recommendation and using it would be under your own risk.
Have you checked with the support from your OEM? They could have an specific procedure to remove software from your device that could help.
If you require any further information or support, feel free to contact us back.
