Not really. “Latinx/Latin(x)/LatinX”, in both English and Spanish (though it seems to be used less in Spanish, even by people who use it in English [0]) is usually, perhaps exclusively, used as an adjective, not a noun.
[0] e.g., I’ve see groups use things like “Soy Yo Latino / I Am LatinX”.
If it is indeed used only as an adjective, it would make sense to see it very rarely in Spanish, as Spanish already dictates which gender to use for an adjective - if you want to say 'a latinx movie' in English to avoid using Latino/Latina, that makes some sense; but in Spanish, 'una pelicula latino' would never make sense, so why use 'latinx' instead of the normal agreement 'latina'?
Not quite on the level of an American college newspaper I saw in the 1990s that identified Winnie Mandela as an African-American speaker when she was making an appearance, but the same kind of process.
