I've seen some interesting projects floating around, at least ghacks.net has created articles. I already install the drivers manually from nvidia.com and use the custom installation option with only the GPU driver and Physx selected. I would much like disabling telemetry, especially if there's any real performance benefit. Optimally this tool would modify downloaded Nvidia installer packages, allowing to keep your system up to date. In the past the Shield-related Nvidia stream service was enabled by default, but thankfully it doesn't seem to ship with the Nvidia drivers anymore.
