Think I've just ran into this on an M2 Mac Mini plugged into a Dell D6000 dock (I'm running 3 displays, one natively via the onboard Mac Mini HDMI port and the other 2 via the Dell D6000) as mentioned here https://discussions.apple.com/thread/255199372?answerId=259919751022#259919751022
Doesn't appear I can use it currently with either of the 3 displays
