Is it possible to detect if a Router WPS button has been pressed or not by just passively monitoring traffic?

I mean you could check if the wps button has been pressed or not using this command > wpa_cli wps_pbc But i am wondering if it's possible to do it using airodump-ng Without any one connecting to it. The wifiphisher Utility claims to be able to do it , even that i wasn't able to find any info about a ready tool that does that and the python code isn't clear enough so i can't tell how they do it Trying to figure out a method to do it passively to add it to a possibly new attack vector Thanks
