You don't have to disable anything, you just increment the row

I already posted that you likely do. Unless you can perfectly match the
turn on and turn off times of the drivers regardless of load. Just banging
a new set of drives on the matrix will result in the new column momentarily
driving the old row or vica versa which creates a faint ghost image.
