two different questions here
"Is there a way to retrieve the firmware from the board on my 3d printe" yes there are ways to copy the firmware off of the controller in some cases... how depends on the chip type.
"Firmware settings retrieval"
Yes and no
There are ways to embed the setting into the firmware, but it is very unlikely that they enabled it
If they enabled CONFIGURATION_EMBEDDING if you send the machine a M115 it will have the line CONFIG_EXPORT 1 and you can extract the configuration file.
If not all you have is M503 Report settings, which is far from complete but better than nothing
