I asked about that in a other post and was told that it was not supported by LibreElec at all but Kodi Android would support it.
My plan was to get a nVidia Shield Pro but if not supported by LibreElec then that's no godd.
nVidia Shield / Shield Pro is the Team Kodi reference device for Android so in the past we've never bothered to investigate support, and in the future it becomes technically impossible (or complicated beyond the point where it's worthwhile) because the nVidia video driver stack isn't compatible with the GBM/V4L2 direction Kodi is taking for Linux. Android is not without occasional faults in Kodi, but the main issues are vendors not following Google API standards. The shield seems to have fewer quirks and is better maintained (has updates) compared to other devices.
