Thanks, i tried it. But it does not work

can you show the code that you have tried

<record id="sale.action_orders" model="ir.actions.act_window">

<field name="name">Sales Orders</field>

<field name="view_mode">tree,form,calendar,pivot,graph,activity</field>

</record>

I removed kanban in view mode. It does not work @niyas

Can you open the corresponding action from the ui, and confirm it still have the kanban in the view mode or not.

I have tried this from ui and get succeeded

Yeah! You are right. Actually , In sale order form (v14),It shows the kanban view and i could see kanban icon. But in edit action, It does not have kanban in view mode.

Thanks! It works for all forms except sale order.
