Noise when applying brakes in park

[Mr. Ploppy]

Hello all. I have a 2021 Bronco Sport Base edition with 51K miles on it. Recently I've been experiencing a light, vibrating, chirping noise, upon start up when applying the brake in park. It only makes the noise when pressing the brake. Today the noise increased from the light sound to a much louder grindy, winy, sound. It only does this on cold starts, and goes away once I'm in gear and driving. Anyone else experience this or have any ideas what it could be?
