To force an update to a version not meant for my device(s)? No, I don't think so. Unless you have an Inoi R7, those updates are not for you. If the settings menu tell you there's no update, then you are on the latest version for your device, period. It would take some kind of obsessive-compulsive need to always be on the highest version number made available by Jolla to update via the command line at that point - and any negative consequences thereof would be highly deserved.
