I have an entity "appointment" with a date_appointment attribute. I have also created a Calendar view for that appointment. An appointment should never be scheduled on weekends, so I have disable those days in odoo datepicker (in the doem view). But when I clic on any Satursday or sunday in the Calendar view it shows the form view where I can create an appointment for that day. Is there any way I can disable those days in Odoo Calendar, so the user cannot clic on any weekend an create appointments. I have already disable the quick_add option

<record id="appointment_view_calendar" model="ir.ui.view">
    <field name="name">appointment.view.calendar</field>
    <field name="model">tico_hospital.appointment</field>
    <field name="arch" type="xml">
        <calendar string="Consultas programadas" mode="week" date_start="date_appointment" quick_add="False" color="patient_id">
            <field name="patient_id"/>
            <field name="reason"/>         
        </calendar>
    </field>
</record>
