> hold down the flush lever
That's not what's being suggested. Slowly open the valve by slowly pressing the lever to let some water in before the valve pop all of the way open.

Plus toilets are designed to prevent you from doing that, they try very hard to be either fully closed, or fully open.
And, even if you succeeded, by releasing some water in advance, you reduce the pressure of the flush, which would elongate it, instead of rapidly removing the material, and time with water flowing = amount of aerosol.
This plan seems counterproductive.
