Rolf van Kleef - Is there a way to set NMEA-200...

Is there a way to set NMEA-2000 identification information? I see in https://github.com/SignalK/n2k-signalk/blob/14eebdfc56ac4d792e2b6c5b7a1772a6a6187ab8/n2kMapper.js#L359 that there are some properties pulled from somewhere, but I cannot find where I can modify these.

What n2k adapter are you using and what exactly do you want to change?

I use an mcp2515 connected through SPI to a Raspberry P 5. Stuff is working using CanboatJS configured for SocketCAN. As I linked, SignalkK sends several identification PGNs over N2k, and I want to adjust that data to differentiate different devices running Signalk.

Here's the relavent code in canboats https://github.com/canboat/canboatjs/blob/65fd6e8764f9c7994f7b2d817d22981120f103bf/lib/n2kDevice.js#L37

You can manually set the addressClaim, productInfo and also the install info. This is done in ~/.signalk/settings.json for example: 
      "pipeElements": [
        {
          "type": "providers/simple",
          "options": {
            "logging": false,
            "type": "NMEA2000",
            "subOptions": {
              "type": "canbus-canboatjs",
