I don't think Trump actually won Hispanics in the rural TX panhandle/southwest NM/southern Colorado. I made a thread about this a while back but looking at precinct level results, it seems like White turnout in these places was much higher and heavily lopsided Republican it diluted the low turnout Hispanic and gave the impression they voted for Trump. In reality, it seems these Hispanics voted similar to RGV Hispanics; swung hard right but still voted narrowly Biden. It was def a close call though, and the true answer may depend on how broadly you define Hispanic.
May have in some counties where GOP topped 90%. In places like King County, Texas or Roberts County, Texas, population quite small and communities close knit, even Latino minority very assimilated into community so wouldn't be surprised in those if vote same way. CNN did a story on Roberts County, Texas after Biden won and almost all the people they interviewed including Latinos supported Trump. But then again those are counties with very small populations and you are probably right in larger ones like Randall County, Lubbock County Biden did probably win the Hispanic vote but turnout fairly low.
Certainly with Native Americans this was true as I noticed a few majority Native-American counties that Trump won, but when you look at precinct breakdown, its clear they went massively for Biden, just turnout was substantially lower than amongst whites thus why Trump was able to win county.
