A lot of the “UBI” experiments that have been done haven’t really been UBI in that they haven’t been universal. Most have been very localized and limited, almost always with some form of means-testing. At least in the USA, the closest we’ve come to truly universal UBI is the Alaska Permanent Fund but even there the amounts doled out have been rather small, never having exceeded $4,000 a year.
We did have a couple of Covid relief payments but they weren’t ongoing and they were means tested.
“Conservatives” in the U.S. may have whined about those payments being socialist but I don’t remember seeing a single story about anyone refusing the payouts as a matter of principle. Everybody seems to have accepted the money.
