ffmpeg command to encode video with same parameters than the gopro 11 - ffmpeg

Question

I want to concat two videos with ffmpeg. In order to concat the videos without re-encoding the videos have to be exactly the same format (same codec, same width, height, same color format, same time base, same frame rate, etc)
One video is from a gopro 11 (and I do not want to re-encode or modify this video)
and the other video is encoded with ffmpeg
ffprobe of the gopro 11 video shows
Stream #0:0[0x1](und): Video: hevc (Main) (hvc1 / 0x31637668), yuvj420p(pc, bt709), 1920x1080 [SAR 1:1 DAR 16:9], 38030 kb/s, 23.98 fps, 23.98 tbr, 24k tbn (default)

The second video is generated with ffmpeg with this command
ffmpeg -i in.MP4 -pix_fmt yuvj420p -tag:v hvc1 -c:v libx265 -x265-params "level=5.1:bframes=0" out.mp4 -y
ffprobe of the generated video is

which is very similar BUT not the same. there is a new extra line
"field_order": "progressive",
that does not appear in the ffprobe of the gopro 11 video.
when I try to concat both videos the final video does not work because the input videos are not exactly the same.
Why does the gopro 11 video not have the field_order parameter?
what can I change in the ffmpeg command to generate a video without the field_order progressive?
Is the field_order the only encoding difference that does not allow the concat?
the first line of the ffprobes show the differences too
