QuickApps do not offer a property to disable jQuery included. I will log an enhancement request for this. In the meantime, as a workaround, users could rename the jQuery file included with QuickApps on each Web Front-end server so to diable the version we loaded. Or make it a blank file so there is no JavaScript loading error. The file can be found at SharePoint Template/Layouts/QuestSoftware/jQuery folder on the WFE server.
