It is an interesting question...
I would guess, that the UX does not.
I think(?), and I will need to check my manual, that my aged RX 300 ( 2003/4), does?
I know it has the rear heated of course, but also can see that it has the front screen elements, across where the wipers sit - and vaguely recall mention of heated jets?
I also use a good quality screen wash - I like Prestone Extreme, and use Prestone to de-ice - as I do not like scraping the windscreen...
