Questions about VBR High Quality NVENC with FFmpeg

Good morning!
I am a happy user of Davinci Resolve and have recently started using FFmpeg for the conversion of codecs that Resolve cannot open.
I am currently trying to encode with FFmpeg in H264 – NVenc in order to arrive at the same export quality as Resolve (NVIDIA encoder) but I still can’t get to that quality.
I think the problem is because FFmpeg doesn’t accept -rc: v vbr_hq (VBR High Quality) but only -rc: v vbr (VBR).
I don’t understand why since -rc: v vbr_hq is one of the H264 options of FFmpeg.
Can someone help me?

I am a Windows user.

Thanks!

ffmpeg -c:v h264_nvenc -preset:v p7 -tune:v hq -profile:v high -level 5.1 -rc:v vbr_hq -coder:v auto -b:v 0 -maxrate:v 25000K -bufsize:v 25000K
