There are some things you can do to remedy this.
1: use a hacksaw or dremel to cut a straight groove in line with the rotation of the disk, about 1/8 inch deep.
This breaks up the harmonics some and gives a channel for brake dust to exit.
2: bevel the edges of the pads. This takes the edges off the disk.
3: There should be a plastic ring that goes between the piston and the back of the pad. if this is broke or missing, replace it. It stops the harmonics between the metal of the pad and the piston.
4: Some high temp brake assembly grease, make sure it is good stuff, and smear it on the metal part of the pad but be super careful to NOT get ANY on the pad material or it will contaminate it and make the pad work poorly.
I have done the 1st 3 and I have 0 squeak. When squeak does happen, I dremel the groove more and bevel the edges again and it is good.
OH #5, rub the pad directly on find grit sandpaper to remove the glaze that forms. that can help too.
The ride IS the adventure. The destination is just to get gas!
