Confusing - these separate functions. Citing NVidia in this case, here's the distinction as I read it...
In options, the hardware DEcoder is being enabled, to facilitate decoding during editing (CUDA).
In produce or create, the hardware ENcoder functions with certain formats, but only with NVidia driver 337.88 or earlier - to enable faster video rendering. This, irrespective of whether DEcoding is enabled in options.

Preference > Hardware acceleration > Enable OpenCL technology
This feature determines what technology is to be used for these specialized effects (the ones with the GPU logo in the corner) when applied to the timeline. When activated the GPU will be used during preview and render. So IF "Enable hardware encoding" in "Produce" is selected as well as this option, these specialized effects if used in the timeline will get the assistance of the GPU and the video will be hardware encoded with the GPU. If this option is unselected, but "Enable hardware encoding" is selected, the video will be hardware encoded by the GPU but these special effects will have the CPU do the task.
Likewise when previewing a video in the timeline that has one of these special effects applied. If this option is selected, the GPU will assist in the render to the playback window, if not selected, the CPU will do the effect task.
Preference > Hardware acceleration > Enable hardware decoding
Is pretty self explanatory, it only affects decoding, nothing to do with encoding so does not affect the ability to "Enable hardware encoding" in "Produce"
Produce > Fast video rendering technology > enable Hardware video encoder
Again, pretty self explanatory, if your GPU supports hardware encoding, you can enable this feature. When enabled, the encoding will be done with the GPU, when unselected, encoding is done with the CPU. Whether faster or slower or a change in output quality really depends on the hardware involved and the timeline contents.
