Another approach for only extending this one form view is to set the field dynamically to readonly when filled.
<record id="view_attachment_form" model="ir.ui.view">
<field name="name">disable remove button if filled</field>
<field name="model">ir.attachment</field>
<field name="inherit_id" ref="base.view_attachment_form" />
<field name="arch" type="xml">
<field name="datas" position="attributes">
<attribute name="attrs">{'invisible':[('type','=','url')], 'readonly':[('datas', '!=', False)]}</attribute>
</field>
</field>
</record>
And a part of the original view:
<sheet>
<label for="name" class="oe_edit_only"/>
<h1>
<field name="name"/>
</h1>
<group>
<group>
<field name="type"/>
<field name="datas" filename="datas_fname" attrs="{'invisible':[('type','=','url')]}"/>
<field name="datas_fname" invisible="1" attrs="{'invisible':[('type','=','url')]}" class="oe_inline oe_right"/>
<!-- and so on -->

If you want to remove the Button for the whole Binary field widget in Odoo, you could just "extend" the QWeb template for that widget, which is:
<t t-name="FieldBinaryFile">
<a t-if="widget.mode === 'readonly'" href="javascript:void(0)" class="o_form_uri"/>
<div t-if="widget.mode !== 'readonly'" class="o_field_binary_file">
<input type="text" class="o_input"
readonly="readonly"
t-att-name="widget.name"
t-att-tabindex="widget.attrs.tabindex"
t-att-autofocus="widget.attrs.autofocus"/>
<button type="button" class="btn btn-sm btn-primary o_select_file_button" title="Select">Upload your file</button>
<button type="button" class="btn btn-sm btn-default fa fa-pencil o_select_file_button" title="Select"/>
<button type="button" class="btn btn-sm btn-default fa fa-trash-o o_clear_file_button" title="Clear"/>
<span class="o_form_binary_progress">Uploading...</span>
<t t-call="HiddenInputFile">
<t t-set="fileupload_id" t-value="widget.fileupload_id"/>
<t t-set="fileupload_style" t-translation="off">overflow-x: hidden</t>
</t>
</div>
</t>
You can extend QWeb templates but have to load them in the manifest file under key qweb.
xml file normally in module at /static/src/xml
<templates>
<t t-name="web.FieldBinaryFile" t-extend="base.FieldBinaryFile">
<t t-jquery="button[title='Clear']"
t-operation="replace" />
</t>
</templates>
And the part of the manifest
{
'name': 'remove button in binary widget',
# and so on
'depends': [
'base',
],
'qweb': [
'static/src/xml/remove_button.xml'
],
# and so on
}
