Got it working.

Tone mapping is handled with these parameters in the video filters section.

zscale=transfer=linear,tonemap=clip,zscale=transfer=bt709,format=yuv420p

I have not tested if the scaler can be before the tone mapping (fewer pixels to tone map?).

Code:

/usr/lib/jellyfin-ffmpeg/ffmpeg
-init_hw_device vaapi=va:,driver=iHD,kernel_driver=i915
-init_hw_device qsv=qs@va
-filter_hw_device qs
-hwaccel qsv
-hwaccel_output_format qsv
-i 'Dungeons and Dragons - Honor Among Thieves.mkv'
-map 0:v
-map 0:a
-map 0:s
-map_chapters 0
-c:v hevc_qsv
-preset slower
-profile:v main
-pix_fmt nv12
-c:a copy
-c:s copy
-ss 0.000000
