How to change commutativity of a SymPy symbol after creation?

Suppose I create a SymPy symbol x.

import sympy as sp
x = sp.Symbol('x', commutative = False)

How can I change the commutative assumption to True without creating a new Symbol? I tried

with sp.assuming( sp.Q.commutative(x) ):
    print( sp.ask( Q.commutative(x) ) )

But it still gives False.
