hello,

Edit and Create button are managed by setting access rights using xml and csv.

To hide Edit set permission write to false.

    <record model="ir.rule" id="ir_values_my_costume_rule">
        <field name="name">My Rule Name</field>
        <field name="model_id" ref="model_your_model_name"/>
        <field name="domain_force">[('field','operator','value'),('user_id','=',user.id)]</field>
        <field name="perm_read" eval="True"/>
        <field name="perm_write" eval="False"/>
        <field name="perm_unlink" eval="True"/>
        <field name="perm_create" eval="True"/>
    </record>
