Your source is 5120x2560, it's not supported by NVDEC. NVDEC supports up to 8192x8192 with other codecs -- HEVC and VP9. See the support matrix under Supported Format Detail for all supported resolutions per codec, per GPU iteration. So if you can provide an input to ffmpeg in one of those formats and your GPU supports these codecs and resolutions, then NVDEC hardware acceleration should work.
