 Impermissive Bayesianism is the view that says “yes”; permissive Bayesianism says “no”. The question of uniqueness is often addressed in a way that is somewhat orthogonal to the question of norms, as is suggested by the ‘whether-or-not’ clause in the parentheses. Moreover, the uniqueness question is often debated in a broader context that considers not just credences but all possible doxastic states, thus going beyond Bayesian epistemology. Readers interested in the uniqueness question are referred to the survey by Kopec and Titelbaum (2016).
