Hello Nitish,
You can specify the scales in the gantt.config.scales
parameter:
https://docs.dhtmlx.com/gantt/desktop__configuring_time_scale.html
gantt.config.scales = [
{ unit: "year", step: 1, date: "%Y" },
{ unit: "month", step: 1, date: "%F" },
{ unit: "week", step: 1, date: "%W" },
{ unit: "day", step: 1, date: "%d" },
];
Here is the snippet:

If you want to switch between the scales, it would be easier to use the zoom extension:
