Personally I'm not able to do so and never heard anyone else claim to possess that ability either. That is not to say I don't believe it might be possible to some - I just haven't come across it.

Before my own ADHD diagnosis and treatment my hyperfocus used to kick in at the most random times and it often lead me to spend far too much time on tangential or superfluous tasks or topics. My medication allows me to channel the hyperfocus into more productive directions, but it still happens when it happens.
