WDDM driver exposes only 384 MB VRAM, at least 512 MB needed (and 12 GB available!)

Description
How does the WDDM driver determine the amount of VRAM to expose?
Our CAD software (Autodesk Fusion 360) checks for at least 512 MB VRAM. The WDDM driver presents only 384 MB VRAM so the CAD software reverts to software rendering.
The physical hardware has 12 GB VRAM (NVIDIA Titan X). Is it possible to tweak the WDDM implementation to provide more VRAM?
Host is Ubuntu 4.0.0-040000-generic and guest is Windows 7 x64 SP1.
Thanks
