Did Paul Dirac believe in multiple universes?

Prominent physicist Paul Dirac proposed a hypothesis that indicated that constants and laws of physics would evolve with time into different constants and laws of nature (https://en.wikipedia.org/wiki/Dirac_large_numbers_hypothesis)

This hypothesis was used by Robert Dicke (https://en.wikipedia.org/wiki/Robert_H._Dicke) to argue in favour of the anthropic principle and the existence of multiple universes each one with its own set of rules and laws.

While Dicke modified Dirac's hypothesis, I have read that Dirac himself once said that 'Dicke's reasoning was sound'.

Does that mean that Dirac, like Dicke, considered the existence of multiple universes with their own set of rules?

Dicke was reasoning from a presumption of multiple universes and that was the reasoning Dirac would have been agreeing with. This says nothing as to whether Dirac agreed with the premise. This is my speculation but I would suspect that Dirac was agnostic on the matter, no positive belief but no way to prove otherwise.
