I don't think there is any solid basis to say this.
There has been at least one study that linked greater differences between right and left prefrontal cortex blood flow, favoring the right, to greater ADHD symptoms.

But developmental differences are pervasively correlated, without contributing to common phenomena, even more so for proximate phenomena, because developmental signals have widespread cascades of impact throughout the body.
This makes the bar for causal claims very high.
There could be no functional correlation, just developmental correlation.
The difference could be causally reverse. I.e. differences in lateral PFC development generated the differences in circulatory recruitment, not the other way around.
Or there is some functional-physical causation, but ADHD is correlated with many other brain differences too. So is it significant?
Then, even if it were significant, Would reducing/increasing blood flow between the post-development sides really have net benefit now? Seems unlikely that any decrease anywhere, even with increases elsewhere, post-development, would be uniformly helpful.
And finally, increasing blood flow is completely different from a re-balance.
Increasing blood flow, or simply increasing oxygen in available air, improves the function of almost everything in the body. Everyone will benefit from more oxygen to the prefrontal cortex, up to a point.
