The drivers on Linux and/or Windows might not support it yet, but NVIDIA's 8th generation PureVideo HD video decode engine ("VP8") available in all the GeForce GTX 10-series (codename "Pascal") of graphics cards supports Nvidia VDPAU Feature Set H, meaning it should even be capable of HEVC Main 12 (12-bit) hardware-accelerated decoding up to 4096 × 2304 pixel resolution, and even higher resolutions for HEVC Main 8 (8-bit) and HEVC Main 10 (10-bit).

Not exactly sure on the details of 10-bit and 12-bit bit dept VP9 decode as wikipedia only state VP9 hardware decoding video decoding up to 4096 × 2304 pixels resolution. People in doom9.org report that the GeForce GT 1030 have fixed-function HW decoder for 10bit VP9 that have been tested by with YouTube 4K HDR clips.

You of course need each and every part in the full chain to actually support playback those the type files in Kodi with hardware-accelerated decoding. Like example, even if & when Nvidia adds support for HEVC Main 12 (12-bit) in their drivers you still have to wait until both FFmpeg & Kodi add support for it too, and vice versa if the case is reversed. All parts need to support it. It's a SPOF (Single Point Of Failure) chain:

Kodi's core video player with render and demux (including depencies on FFmpeg) => HW decode API support => Manufacturer device drivers for the OS => Capable HW video decode engine.
