RTXVideoSuperResolution outputs all-black on Linux + RTX 50-series (Blackwell)

A user reports that the RTXVideoSuperResolution node in ComfyUI produces all-black output on Linux with an RTX 5060 Ti (Blackwell). Debug logs reveal a missing kernel image for the architecture (sm120). Further investigation suggests the official Linux VFX SDK Core on NGC lacks support for GeForce consumer cards in the installer script, and access may require an NVIDIA AI Enterprise subscription, structurally blocking the feature on Linux for consumer GPUs.
