I am not particularly concerned about HiveMQ ... My issue is wanting to modify the username, password, port, and URL

But those details will be entirely specific to HiveMQ and how you are using it - cloud? local server? etc ...

HiveMQTT neither knows nor cares what microcontroller you use - these things would all be the same irrespective of your platform.

I suggest you start by reviewing these basic principles in the HiveMQ documentation, and general MQTT documentation, tutorials, etc.

https://mqtt.org/

Do you have basic TCP/IP working?
