No, you can’t change the blink-rate.
On standard VGA adapters the blink attribute switches between on and off every 16 frames, so 60 frames/second you get around 1.8 blinks/second.
Most VGA adapters have extensions to the standardized VGA interface that may or may not allow to change the blink-rate. You could use this if your adapter has support for it and if you are able to get your hands on the chip documentation, but it will not work for other adapters and will not be portable.
