Render in davinci resolve using ffmpeg

I want to cut some clips from main video ande export it without re-encoding. Just copying stream. in davinci resolve, but use ffmpeg, is it possible?

i have main video fo example 60 seconds long
i cut some moment via davinci resolve and get new video 40 seconds. (i didnt add new text or images inside video just cut)
i want to export new 40 second video without decoding like it was using with ffmpeg command

ffmpeg -i 60sec.mp4 -c:v copy -c:a copy 40sec.mp4

for example i can use this in software named xvid4psp. i should just choose “Copystream”

question can i use ffmpeg inside the davinci resolve to copystream after cutting the material?
