It is possible to load the options of a parameter dynamically with loadOptions

One example of that is, for example, the AWS Lambda-Node where it loads the different functions via an API:

n8n-io/n8n/blob/9785680882c0d141cff5d9444de262bd5cd59565/packages/nodes-base/nodes/Aws/AwsLambda.node.ts#L130

      
        
            				default: '',
            				description: 'The JSON that you want to provide to your Lambda function as input',
            				typeOptions: {
            					alwaysOpenEditWindow: true,
            				},
            			},
            		],
            	};
            
            
	methods = {
            		loadOptions: {
            			async getFunctions(this: ILoadOptionsFunctions): Promise<INodePropertyOptions[]> {
            				const returnData: INodePropertyOptions[] = [];
            
            
				let data;
            				try {
            					data = await awsApiRequestREST.call(this, 'lambda', 'GET', '/2015-03-31/functions/');
            				} catch (err) {
            					throw new Error(`AWS Error: ${err}`);
            				}

What is however sadly not possible, is to create different parameters. The parameters are currently fixed, only the values can be loaded dynamically.
