Good afternoon.

Thanks for the advice, but my laptop does not have the necessary drivers installed.

At the technical support website says that my device is only supported by MS Windows 10.

For the Windows 7 operating system there are no touchpad drivers available for download.

I use a laptop at the work and Windows 7 is our corporate standard.

Is there a driver or program for the touchpad for OS Windows 7?

Or it is possible to disable the touch panel via BIOS?

You could install a free utility call Touch freeze. It will shuts down the touchpad soon as you begin typing, also  turns it on when you stop. Please click on link below:
