How to remove "Add New Customer" in Index Admin Customer:
I created a new module:
Create 2 file:
1) NameSpace/Module/view/adminhtml/layout/customer_index_index.xml
<?xml version="1.0" encoding="UTF-8"?>
<referenceContainer name="content">
<uiComponent name="customer_listing">
</uiComponent>
</referenceContainer>
2) NameSpace/Module/view/adminhtml/ui_component/customer_listing.xml
<?xml version="1.0" encoding="UTF-8"?>
