1. Hide 'Delete' and 'Move' buttons from child table rows

(Sales Invoice - DocType , Sales Invoice Item - ChildTable)

frappe.ui.form.on('Sales Invoice', {
    refresh(frm) {
    }
})
frappe.ui.form.on('Sales Invoice Item', {
   form_render(frm, cdt, cdn){
       frm.fields_dict.items.grid.wrapper.find('.grid-delete-row').hide();
       frm.fields_dict.items.grid.wrapper.find('.grid-move-row').hide();
   }
})

2. Hide checkboxes of child table rows

frappe.ui.form.on('Sales Invoice', {
    refresh(frm) {
            cur_frm.fields_dict.items.$wrapper.find('.grid-row-check').hide();
            cur_frm.fields_dict.taxes.$wrapper.find('.grid-row-check').hide();
    },
})

3. Hide 'Add Rows' button

frappe.ui.form.on('Sales Invoice', {
    onload(frm) {
        frm.get_field('items').grid.cannot_add_rows = true;
    }
})    

4. Hide Timeline

frappe.ui.form.on('Sales Invoice', {
    refresh(frm) {
        document.getElementsByClassName("timeline-items timeline-actions")[0].style.display = "none";
    }
})

5. Hide Buttons in Form View

frappe.ui.form.on('Sales Invoice', {
    refresh(frm) {
    setTimeout(() => {
        frm.page.remove_inner_button(__('Payment'),  __('Create'));
        }, 10);
    }
})
