Hi Sourabh,
Greetings from Syncfusion.
The drilldown functionality is supported for all chart types
and this is achieved by updating the chart series data points using refresh
method in pointClick event which is triggered which clicking a point in
a chart series. We already have an online demo for pie chart. Please check with
the below link.
Pie : https://ej2.syncfusion.com/angular/demos/#/bootstrap5/chart/drill-down-pie
We have prepared drilldown sample for column chart. This
same approach is applicable for all cartesian type charts.

Please revert us if you have any concerns.
