I also tried to install intel media driver. But that also didn’t help. NoMachine is still using software encoder. Any help is appreciated.
I did that. Still getting errors. session logs below.

I did more experiments like below.
1. Installed intel media driver as mentioned in https://www.nomachine.com/AR09O00938 ( except kernel changes )
2. Installed intel-media-driver from AUR ( arch repo ).
vainfo fails like below in both cases. Library is present in that location which I have confirmed.
libva error: /usr/lib/dri/iHD_drv_video.so init failed.
3. When I set this environment variable ( export LIBVA_DRIVER_NAME=i965 ) vainfo seems to be working fine. I get the following output.
vainfo: VA-API version: 1.7 (libva 2.7.1)
vainfo: Driver version: Intel i965 driver for Intel(R) Haswell Desktop – 2.4.0

Still NoMachine uses software encoder only. Looks like NoMachine doesn’t work with both iHD and i965 drivers. Any help is appreciated.
The problematic part at this point is between the Intel driver and libva – which we can’t do much about it, because it’s not a part of NoMachine. We can only provide instructions on how to make it work. Even wth NoMachine OUT of the picture, it’s a struggle in general to make Quicksync work on Linux.
1. Installed intel media driver as mentioned in https://www.nomachine.com/AR09O00938 ( except kernel changes )
Kernel changes are fundamental to make it work. The steps we’ve got in article are from Intel itself, so there’s a reason they included changes to the kernel to make it work.
