Depending upon your location - it is possible the disc brake rotors are developing surface rust while parked overnight .. That's a fairly common problem .. After applying the brakes a few times the surface rust is wiped away by the brake pads and the noise is no longer present - until the process is repeated all over again.
Recommend hands-on inspection of all brake pads and rotors just to be safe. https://repairpal.com/repair-shops
