No. Nothing to do with Whitehead. The only connection to Parmenides is that Parmenides was an early Greek rationalist who argued for the undifferentiatedness of being, i.e. that all change and differentiation is illusory and everything is ultimately just one uniform (and spherical) "being."
We don't know much about Parmenides because we only have fragments. They are some of the most disputed and reinterpreted fragments in the history of philosophy, but the general consensus on them is usually that they are rationalistic and logical arguments for the illusoriness of becoming. He also apparently inspired a school of people who had similar arguments, like Zeno's famous paradoxes aimed at showing motion and change etc. are impossible. Some interpretations wonder whether Parmenides' extant rational philosophy was just the exoteric side of an esoteric and mystical philosophy, but these are only hints and suggestions. We know almost nothing concrete about early orphism or other Greek mystery traditions, although they seem to have existed.
The Guenon spammer learned about Parmenides on some Wikipedia binge, or in some traditionalist footnote making the facile association between his philosophy and Shankara's nondualism, which is actually more or less Mahayana nondualism turned into a paradoxically nihilistic absolute idealism. Mahayana is also fairly late so it may have been in significant dialogue (we really don't know) with Greek and even Christian ideas, and since Shankara's Advaita philosophy is nearly completely reliant on Mahayana's framework, any influences or resonances with Greek thought would obviously be carried over.
