You could wrap the video stream into an mkv container and add the flags to the mkv container.
Alternatively, read up on the standard and check whether the standard supports those flags in the video stream itself. I'm pretty sure it does not.
Last I checked, MPEG-1 should always have 4:2:0 chroma sampling, TV luma range and use a bt.601 color matrix.
A quick internet search should have shown this.

It is in a mkv container. How do I add them using ffmpeg?

oh... MPEG-1 with BT709 in FULL HD? Ouch. That's... weird... to say the least...
I'm not sure this is gonna work, but you could try with a simple:


ffmpeg.exe -i "input.mkv" -c:v copy -c:a copy -aspect 16:9 -color_range 1 -color_primaries 1 -color_trc 1 -colorspace 1 -y "remuxed.mkv"


and see what comes out at the other end.

Alternatively use mkvmerge (https://mkvtoolnix.download/doc/mkvmerge.html#d4e2979).
