Hi,

You can remove edit button by changing write access of a model to '0' in security files or by setting edit = false in that models form view.

eg:

<record id="sales_commission_form_view" model="ir.ui.view">
    <field name="name">sales.commission.form</field>
    <field name="model">sales.commission</field>
    <field name="arch" type="xml">
        <form create="false" edit="false" delete="false">

Regards
