 The NVIDIA files are not covered by d4r's license; redistributing them is up to whoever publishes the zip. `D4R_BUNDLE_NVIDIA=0` builds `d4r-<version>-nonvidia.zip` without them and without the texture kernels. [architecture.md](architecture.md#portable-installs-the-release-zip) describes how the installed files work together.
