It is expected that driver options likely meant for d3d games will not work when the game outputs Vulkan through dxvk.
Putting d3d9.forceSampleRateShading = True into a dxvk.conf next to the game exe is your friend.
As was mentioned, the Nvidia driver options do not apply to Vulkan, this is not a bug.

Please describe your issue as accurately as possible. Include screenshots or videos when relevant.
Activating MSAA ingame is not the problem but the option in the nvidia driver for AA Transparence(Supersampling) does not work and thats relly bad because it makes the picture heavy flickering and ugly(leaf, grass, flowers, meshes... everything which use transparent textures)
