I heard couple claims that Nachmanides had the belief that the Shechinah is not a caused and distinct emanation but rather God himself or even a person (hypostasis) according to some Christians, the Artscroll edition of Ramban's commentary and I read it on Sefaria which the translation seems to hide this by using translation to say "created for the occasion" when it simply says נברא. I will be quoting the Hebrew for people to CTRL F. Another reference is Ramban's commentary on Genesis 46:1,1 on Sefaria. So did Ramban believe in another uncreated entity besides God, or not?
והמתפלל לכבוד נברא כעובד אלילים
על שם השכינה שהוא האל יתברך
