BiblicalArchaeology.org confirms that the Kuntillet Ajrud inscriptons mention Asherah. These inscriptions were found on large storage containers, but according to this website, some scholars have interpreted both figures as male. Furthermore, another article from this website says that there is a plural term for Ashera, Asherim, which may mean that this term refers to a type of deity. It is also mentioned that there are both masculine and feminine forms of this word "asherim" in Hebrew.

The Jewish Women's Archive backs up this claim, saying that "YHWH and Asherah were appropriately worshipped as a pair."

Found sources backing up this claim of Asherah being "demoted", seems it started with uncapitalizing the A.

BYU's Archives confirm this and say that Asherah was seen as the mother of the other gods.
