The light is on top of the dashboard, right in the middle. It's intended to be very visible, especially from outside the car.
It is only on if the car is turned off and parked and the high voltage system has turned on to charge the 12V battery. When you're driving or just have turned on the car while parked, the light goes off.
So the only occasion the light might be annoying is if you're taking a nap in the car at night. And then you could just throw a towel on top of it.
You expect to have the high voltage system energized when driving, otherwise the car wouldn't go anywhere. There would be no purpose for this light to go on.
The light is specifically to indicate that the high voltage system is on when the car is parked. It's a safety warning for that situation.
