Here is my version. No need to list all modules.

const pre_disabled = {
  "UNLISTED": true, // default value for unlisted other modules.
  "alert":false,
  "clock": false,
  "MMM-Remote-Control":false,
 }

var DISABLED = new Proxy(pre_disabled, {
  get (receiver, name) {
    return name in receiver ? receiver[name] : receiver["UNLISTED"]
  }
})

const DISABLED = {};
   
    DISABLED.clock = false;

},

It should just be this:

const DISABLED = {};
DISABLED.clock = false;

It’s that last }, that’s breaking your code.

		{

};

/*************** DO NOT EDIT THE LINE BELOW ***************/
if (typeof module !== "undefined") {module.exports = config;}

Place it at the top of the file, before this line:

var config = {

I’ve done this in my config.js file:

Where do you placesd this in you config. Like this?

	modules: [
			
const DISABLED = {};
   
    DISABLED.clock = false;

}
  
		{
			module: "alert",
			classes:  'default everyone',
			},
		{
			module: "updatenotification",
			position: "top_bar",
			classes:  'default everyone', 
			},
		{
			module: "clock",
			position: "top_left",
			classes:  'default everyone',
			disabled: DISABLED.clock			
		},
		
	    ]

};

const DISABLED = {};

if (RPI_DEV) { // I'm setting this value automatically based on the system
    DISABLED.weather = false;
    DISABLED.clock = false;
    DISABLED.calendar = false;
    DISABLED.tools = false;
    DISABLED.hue = true;
    DISABLED.newsfeed = true;
    DISABLED.nest_cameras = true;
    DISABLED.nest_status = true;
    DISABLED.telegram = true;
    DISABLED.hotword = true;
} else {
    DISABLED.weather = false;
    DISABLED.clock = false;
    DISABLED.calendar = false;
    DISABLED.tools = false;
    DISABLED.hue = false;
    DISABLED.newsfeed = false;
    DISABLED.nest_cameras = false;
    DISABLED.nest_status = false;
    DISABLED.telegram = false;
    DISABLED.hotword = false;
}

And then for each module you can do something like this:

{
    module: 'clock',
    position: 'top_left',
    config: {
        displaySeconds: false,
        displayType: 'digital',
        dateFormat: 'dddd, MMM D, YYYY'
    },
    disabled: DISABLED.clock
},

disabled 	Set disabled to true to skip creating the module. This field is optional.
