You are right. The ISO provided by Microsoft does not contain drivers developed by third parties for their devices.
I also didn't find any official drivers for this device on the Prestigio website.
Unfortunately, It is the manufacturer's responsibility to provide compatible drivers for the device.
Therefore, you need to contact Prestigio to request an ISO that already has the device drivers or request the driver installation files to be installed separately after installing Windows with the ISO provided by Microsoft.
