In the Gantt component, you can set the vertical scroller position dynamically by clicking the custom button using the setScrollTop method.

app.component.ts

import { Component, ViewEncapsulation, OnInit, ViewChild } from '@angular/core';
import { Gantt } from '@syncfusion/ej2-gantt';
import { GanttComponent } from '@syncfusion/ej2-angular-gantt';
import { ButtonComponent } from '@syncfusion/ej2-angular-buttons';
import { editingData } from './data';

@Component({
    selector: 'app-root',
    template:
       `<button ejs-button id='scrolltop' (click)='scroll()'>Set Scroll Top</button>
       <br><br>
       <ejs-gantt #gantt id="ganttDefault" height="430px" [dataSource]="data" [taskFields]="taskSettings" [splitterSettings]="splitterSettings"></ejs-gantt>`,
    encapsulation: ViewEncapsulation.None
})
export class AppComponent{
    // Data for Gantt
    public data?: object[];
    public taskSettings?: object;
    public splitterSettings?: object;
    @ViewChild('gantt', {static: true})
    public ganttObj?: GanttComponent| any;
    public ngOnInit(): void {
        this.data = editingData;
        this.taskSettings = {
            id: 'TaskID',
            name: 'TaskName',
            startDate: 'StartDate',
            duration: 'Duration',
            progress: 'Progress',
            child: 'subtasks'
        };
        this.splitterSettings = {
            position: "50%"
            };
    }
    scroll(): void {
        this.ganttObj.ganttChartModule.scrollObject.setScrollTop(500);
        };
}
