I don't know, The one person that might be able to answer your question, is at the moment ,not active at AMD Forums which is @fsadough AMD Moderator for Professional GPU Cards.
DDU is Display Driver Uninstaller recommended by both AMD and Nvidia Forum Users for removing the current Graphics driver.
You can download it from here: Wagnardsoft DDU Download
But it is also important to delete the AMD installation folder created each time your run a AMD Driver package at C:\AMD.
Using DDU and deleting C:\AMD installation folder will prevent future AMD/Nvidia Driver installation issues.
