If you read the article it mentions that the AMD Driver is for Windows 11 for those Users in the Preview version testers.
AMD has published Ryzen driver version 3.09.01.140 for Windows 11. AMD has said that the update enables all features found in Radeon Software on Windows 11. These features include Radeon Boost, Radeon Anti-Lag, Radeon Image Sharpening, and more.
This update also addresses potential issues with Windows 11 on supported chipsets, including 400-series and 300-series.
“Windows 11 is just around the corner, and we know many users are participating in Microsoft’s Windows Insider Program and have access to an early build of Windows. If you’re one of those people, you can now take advantage of all the features found in Radeon Software,” AMD said in a statement.
Officially AMD doesn't support Windows 11 drivers until October 5 when Windows 11 becomes official so I don't believe AMD Support will answer any questions concerning drivers for Windows 11 yet.
It is best to wait and see what AMD Drivers are posted after Windows 11 release to the public. Personally that driver will probably be the one posted after Windows 11 is official but as far as I am aware AMD doesn't publicly support that OS yet until October 5.
Til then you will need to go through Microsoft Support.
Between now and October 5, Windows 11 can still go through a lot of changes that might affect the AMD Driver for Windows 11 in which case AMD will need to tweak the driver before releasing it.
Once Windows 11 is officially release then AMD will start supporting that OS.
That is my personal opinion from past AMD Moderators comments concerning BETA OSes or upgrades.
