Hello Hemanth, try this 

Option 1: Modify Tree View Default Order

• Inherit the helpdesk ticket list view then add default_order="write_date desc" attribute to <tree> element

Option 2: Track Stage Changes with Custom Field

• Add last_stage_update datetime field and override write() method to update field when stage_id changes
• Then, set default_order="last_stage_update desc" in tree view

Option 3: Save as Default Filter (Quick one)

• Manually sort by desired column then click Favorites → Save current search
• Enable "Use by default"

Let mw know if this helps:)
