Hi, We support it on Jetpack 4.6. Please refer to the command:

gst-launch-1.0 filesrc location=test.yuv ! videoparse
width=352 height=288 format=52 framerate=30 ! 'video/x-raw, format=(string)NV24'
! nvvidconv ! 'video/x-raw(memory:NVMM), format=(string)NV24' !
nvv4l2h265enc profile=High444 ! h265parse ! filesink location=test_yuv444.265

For lossless only YUV444 is supported.
