In Odoo CRM Modul > configuration > Stages, there's a view of CRM Stages, Editable.
How to make it read-only for all?

I'm making a module to update CRM behaviour.

I was expecting something like this could work:

<odoo>
    <record id="myid_readonly" model="ir.ui.view">
        <field name="name">crm.stage.tree.readonly</field>
        <field name="model">crm.stage</field>
        <field name="inherit_id" ref="crm.crm_stage_tree"/>
        <field name="priority">9</field>
        <field name="arch" type="xml">
            <list position="attributes">
                <attribute name="edit">false</attribute>
                <attribute name="create">false</attribute>
                <attribute name="reorder">false</attribute>
            </list>
        </field>
    </record>
</odoo>

odoo.tools.convert.ParseError: while parsing /mnt/addons/mymodul/views/crm_stage_views.xml:16
Invalid view crm.stage.tree.readonly definition in mymodul/views/myviews.xml

View error context:
'-no context-'

I found out that view architecture is:

<list string="Stages" multi_edit="1">
    <field name="sequence" widget="handle"/>
    <field name="name" readonly="1"/>
    <field name="is_won"/>
    <field name="team_id"/>
</list>

Not sure how to put these together.
