You can install what you want on any UT device if you make its file system read/write.
But if you do that, which is not a supported way using UT, you'll be then the only one to deal with any issue, including breaking the system, you could encounter.
AND you'll no longer should make OTA updates as it will overwrite some or all of the customisations you made, with a result depending on which parts where modded (from system bug to device not booting anymore).
If you really want to mess with your UT, search the forum how you can make the system read/write.
There is also a telegram group for people like you that are not feared "breaking" UT.
