It hides the button in the purchase.request form view, but not applied in the purchase.reqeust.line tree view, it is still visible if you toogle some lines in the purchase lines and click the action button.
Thank you.

Sorry I forgot to tell you that the action is defined in the wizard/purchase_request_line_make_purchase_order.xml line 62.
Thank you.

I found solution for this case
In here, action window will open wizard.
So, you update:
<field name="binding_model_id" eval="False"/>

Then, action Create RFQ will hide on purchase.request.line (tree view)

Could you please tell me the detail steps, which id I should inherit?Thank you

In your view,
<record id="purchase_request.action_purchase_request_line_make_purchase_order"model="ir.actions.act_window"><field name="binding_model_id" eval="False"/>record>
