[FFmpeg-user] Add blur-in at a particular time on a video

I am trying to blur a video after 12 second. But I also want the video to
gradually blur for 2 seconds sort of "blur-in" (like you would fade a video
in by changing alpha over time).
I was only able to do a simple blur for the 12 second and on:
ffmpeg -i input.mp4 -vf "boxblur=enable='gte(t,12)'" -strict -2 output.mp4
Can someone help?
Thanks for the help,
