How to Minimize VRAM Usage by nDWM.exe

I have optimized my desktop for peak performance, but it is currently utilizing an excessive 1.3 to 1.7 GB of VRAM, which is unnecessary for my needs. Despite re-installing the Nvidia driver, the issue persists.

As an avid VR gamer, I require maximum VRAM allocation for an optimal gaming experience. How can I effectively reduce the current VRAM usage to only 10-20% of its current capacity or less, without compromising performance?
