Hi Desmond,
Greetings from Syncfusion
Support,
By default, custom columns couldn’t be
included in the segment tab; only default columns are rendered in the segment
tab. To achieve your requirement through workaround(To remove Segment Tab), we
suggest using the GanttEditDialogFields property in the Gantt chart.
This property allows you to render only the necessary tabs in the dialog when
editing or adding tasks. We have attached a code snippet and sample for
reference.

<SfGantt TValue="TaskData" EnableContextMenu="true">
…
<GanttAddDialogFields>
<GanttAddDialogField Type="GanttDialogFieldType.General"></GanttAddDialogField>
<GanttAddDialogField Type="GanttDialogFieldType.Dependency"></GanttAddDialogField>
</GanttAddDialogFields>
<GanttEditDialogFields>
<GanttEditDialogField Type="GanttDialogFieldType.General"></GanttEditDialogField>
<GanttEditDialogField Type="GanttDialogFieldType.Dependency"></GanttEditDialogField>
</GanttEditDialogFields>
</SfGantt>
