Hi,

You could try the below mentioned method to patch js.
/** @odoo-module **/

import { patch } from "@web/core/utils/patch";
import { luxonToMomentFormat } from "@web/core/l10n/dates";

patch(luxonToMomentFormat, 'module_name.luxonToMomentFormat', {
    start() {
        return this._super();
    }
});

Hope it helps
