Hi,

Please check the code below:

<record id="view_partner_form" model="ir.ui.view">
    <field name="name">res.partner.view.form.inherit</field>
    <field name="model">res.partner</field>
    <field name="inherit_id" ref="base.view_partner_form"/>
    <field name="arch" type="xml">
        <xpath
                expr="//div[hasclass('oe_button_box')]/button[@name='your_button_name']"
               position="attributes">
             <attribute name="invisible">Your condition</attribute>
        </xpath>
    </field>
</record>

Hope it helps.

<xpath expr="//header/button[@name='your_button_action']" position="replace">

    <button name="your_button_action" string="Your Button"
