HDR/SDR Tone mapping has long been the bane of hardware transcoding for Plex. Even when it "kinda works" which is Nvidia on Linux only it kills my GTX 1650 in RAM and compute required. Normally NVENC can handle 3 4k Streams or many many 1080p streams, only constrained by RAM.

on quicksync (600 series above igpu, i.e. kabylake/gemini lake) it can do it without an issue. on gemini lake cores, I've done 4 hdr tone mapping (uhd bluray source to avc sdr) without a problem.
