This is entirely plausible in terms of Trump '20 floor in UT absent a serious 3rd Party Contender.
All that said, I would not be surprised to see UT PRES GE % Vote margins a bit less than +19% Trump.
Biden should most likely significantly out-perform Obama '08 in UT, especially if we look at the current ntl % baseline and also look at Trump's "appeal" to many LDS adherents, which needless to say is a bit lacking, not to mention younger Mormons in Utah not necessarily voting the same way that their parents did a few decades back bcs of shifts in generational cultural "value orientation" and themes.
