Please find code is here :-

For example:

<?xml version="1.0" encoding="UTF-8" ?>
<templates xml:space="preserve">
<t t-name="custommodule_name.ListRenderer" t-inherit="web.ListRenderer" t-inherit-mode="extension" owl="1">
<xpath expr="//t[@t-foreach='state.columns']//th" position="attributes">
<attribute name="t-on-click"/>
<attribute name="t-on-mouseenter"/>
<attribute name="t-on-mouseleave"/>
<attribute name="t-att-class"/>
</xpath>
</t>
</templates>

FYI: This will disable the records get sort for all the tree view.
