Hi,
You can extend the ListRenderer and add ev.preventDefault() in the click function. Then, add the new ListRenderer to the registry and include this widget in your field. This solution will resolve the issue.

odoo.define('my_module.list_renderer', function(require) {
"uses strict";
var FieldOne2Many = require('web.relational_fields').FieldOne2Many;
var fieldRegistry = require('web.field_registry');
var ListRenderer = require('web.ListRenderer');
var listRenderer = ListRenderer.extend({
events: _.extend({}, ListRenderer.events, {
'click .o_data_row': function(ev) {
ev.preventDefault();
},
})
});

var listFieldOne2Many = FieldOne2Many.extend({

_getRenderer: function() {
if (this.view.arch.tag === 'tree') {
return listRenderer;
}
return this._super.apply(this, arguments);
},
});
fieldRegistry.add('list_one2many', listFieldOne2Many);
return listRenderer;
});

<field name="one2many_field_name" widget="list_one2many">
