Hi:
You can probably update it as follows, but I think it is going to wreck the switchable graphics setup.
Here's how if you want to roll the dice...
First, create a system restore point so that you can roll back to the current graphics driver you have installed, just in case the updated driver does not work to your expectations.

Next, download and save the latest Intel HD graphics driver 64 bit ZIP file.
15.40.44.5107 (Latest) Date: 1/10/2020

Unzip the graphics driver file to its folder. Do not do anything with the files in the folder.
To unzip the file, right click on the graphics driver zip file you downloaded, and select Extract All.
Go to the device manager, click to expand the Display Adapters device manager category
Click on the Intel HD graphics adapter listed there.
Click on the driver tab. Click on Update Driver.
Select the Browse my computer for driver software option, and then at the bottom of that window, select the Let me pick from a list of device drivers on my computer.
Click on Have Disk, and browse to the unzipped graphics driver folder>Graphics>igdlh64 (setup information file), click Next, and the driver should install.
Be patient, as it can take a few minutes for the driver to completely install.
When the installation is finished, restart the PC.
