Hi Bhanu Gandluri,
Our @IndiumSoftware team has built this custom date picker. You can achieve this use case by using this widget.
Marketpalce Link: https://marketplace.mendix.com/link/component/121037
With the standard date picker this is not possible.
Never used it but this widget seems to be doing what you want: https://marketplace.mendix.com/link/component/121037
Maybe there is another widget in the marketplace that can help!
