Some pages found via a web search seem to indicate that you cannot run the command by calling its name, but have to either use
$ getcert add-ca -c exampleSCEPca -e /usr/libexec/certmonger/scep-submit -u http://ca.example.com/cgi-bin/pkiclient.exe
(source: https://www.admin-magazin.de/Das-Heft/2017/03/Zertifikatsmanagement-mit-Certmonger/(offset)/4 )
or
sudo /usr/lib/certmonger/scep-submit -u ...
(source: https://docs.foxpass.com/docs/install-scep-certificate-on-linux )

Neither were helpful.
