no, but you can install according software (probably php stuff) in websites setup and managed by ISPC.
I think the answer is quite clear. You can build your wanted radio streaming website and manage it with ISPC server. It should work just fine.
It all depends on how you want to set it up. You can ofcourse install the nescary software for streaming and plcae your music files on the server, but it's not supported by ISPConfig. ISPConfig is for - HTTP - HTTPS with letsencrypt (automated) - DataBase - E-mail - DNS - XMPP So if you want to install extra software on your server/vps alongside of ISPC, thats all up to you. You can put in a website to manage shoutcast, but thats about it.
