I don't think so.
It is possible to play hevc interlaced with ffmpeg via mpv but you'll
have to set up your own filter chain and possibly adjust for field order.
I've done it on a homemade (libx265) test. libx265 only takes a certain
field order and expects fields, plus interlaced support is (was) flagged
as experimental. It did seem to work though, it was a while ago so this
is just a paste from notes on the playback side - basically you need to
weave the fields that the decoder outputs as weaved frames is what other
mpv -fs --vf=lavfi=[tinterlace=merge,setsar=1/1,yadif=1] hevc-interl-5M.mkv
