The fans will know what UESPA is, and for a sizable chunk of the general audience coming in, Star Trek's details will be a relative unknown.
There certainly wouldn't be any reason to excluded UESPA, although coming up with a different way of pronouncing it as a word might be a consideration.
I'm going to guess that the producers of DSC have no clue what UESPA is.
Maybe "You-ee spa?"
It was pronouced "you-spah" in the one TOS episode it was mentioned in.
