Windows 7 modifying driver inf file to work on windows 7?

I recently installed windows 7 in dual boot with my windows 10.I got most of devices working by wasting a few hours.But i can't get display driver working.When doing manual instllation through device manager,on clicking on inf file it shows the folder you specified doesn't contain a compatible software driver for your device. if the folder contains a driver, make sure it is designed to work with Windows for x64-based systems .If i do it on windows 10 device manager it works fine so i guess amd has designed inf file to work only on windows 10.So is there anyway i can modify inf file to make it work in windows 7? My graphics card is AMD Radeon(TM) Vega 8 Graphics. Here is link to inf file- Link Removed
