By using the uploading event and its customFormData argument, you can achieve this behavior. Refer to the following example

In the following code snippet, explains about how to add additional data on file upload.

import { Component } from '@angular/core';
import { EmitType } from '@syncfusion/ej2-base';
import { SelectedEventArgs } from '@syncfusion/ej2-angular-inputs';
@Component({
    selector: 'app-root',
    templateUrl: 'default.html',
    styleUrls: ['index.css']
})

export class AppComponent {
    public path: Object = {
        saveUrl: 'https://services.syncfusion.com/angular/production/api/FileUploader/Save',
        removeUrl: 'https://services.syncfusion.com/angular/production/api/FileUploader/Remove'
    };

    public onFileUpload: EmitType<SelectedEventArgs> = (args: any) =>  {
        // add addition data as key-value pair.
        args.customFormData = [{'name': 'Syncfusion INC'}];
    };
}
