No, if anything, it's the other way around. The nobility ranks are basically their "age" minus power they lost through being defeated (in the Spiritual World). It might influence their lower and upper cap in terms of evolution to a certain extent, but the evolution and resulting overall power is ultimately still decided by other factors like what sort of material body they gain and whether they are named and how strong that namer is. They are basically completely separate concepts and evolutions do not affect the nobility ranks.

WN translators had made some mistranslations in the past where the "Peer" evolution was mixed up with the Duke nobility rank (probably because both use the Kanji 公). But the vol. 8.5 databook kind of clarifies this. Though the final line might have some mistakes, as apparently in vol. 11 a "Grand Duke" nobility ranking is introduced for the oldest non-primordial, so Duke doesn't actually seem to refer to primordials, but it's better to leave that aside until the fantranslation for volume 11 is finished, I think.
