If it was me, I would phone the shop it was bought from if under warranty as it may have a fault; if you make enough fuss stating you would never buy this brand again, they may come up with a solution; if you or a tradesman/amateur try disconnecting something you may not be covered under its guarantee if some other fault is found and its found a parts been disconnected.
If it is NOT under guarantee/warranty, I would have thought that there's a way of locating the source of sound and muffling it in some way perhaps with some non flammable material - just a thought. Not sure if disconnecting the flashing diode light would stop the noise?
