A bit. ffprobe is capable of printing only desired fields, check the
lovely example in the wiki:
https://trac.ffmpeg.org/wiki/FFprobeTips#Formatcontainerduration

This command prints the (container) duration in seconds:
$ ffprobe -v error -show_entries format=duration -of default=noprint_wrappers=1:nokey=1 foo.ts
(You might want to add "2>/dev/null". Or just leave it if you use
backticks or the likes.)

You could compare that floating point value against seconds instead of
minutes, or do your math to get the minutes. (I probably wouldn't do
the math with awk, but either directly with the shell, or with bc. But
that's just me.)
