In 2016, exit polls showed Clinton getting 70% of the two-party Latino vote but Biden only got 67%. I looked at the exit polls for Florida and the data for the RGV and found that the vote share for Donald Trump among Latinos in those two areas were 35% and 27%, respectively in 2016. Then, they increased to 47% and 40%, respectively. (I decreased the RGV by 2 percentage point because of non-Hispanic white voters favoring GOP more.)
This looks like it is possible, but I am not sure.
