I would be cautious in making the claim that "Scholars view..." It's lilke saying "Science tells us that..." Scholars often disagree. That's the nature of scholarship.
"Scholars view 'Elyon' as referring specifically to El, not a general 'Most High' god. Why? in Genesis 33:20 Jacob builds an altar in the old cultic center of the north, Shechem, and dedicates it to “El, god of Israel” (’el ’elohe yišra’el ). There is no ambiguity in the Hebrew here: ’el must be translated as a proper name, El. Note that the Dead Sea Scroll and Masoretic Text versions have the same basic version."
EL is a proper name for God in numerous instances in the texts, as well as a generic noun for gods/deities and was used as a title for various pagan deities
The word "ELOHE" in Hebrew is the possessive propositional form of "ELOHIM" meaning "god of". As you know, the Hebrew in the Mesoretic texts do not have an lower case to differentiate el / El between a generic noun "god" or "God" the proper name and/or the ontological ultimate, so the translation can be as easily read as "God, the god of Israel" as "El, the god of Israel."
EL also has a connotation of "might" or "power" in Old Testament Hebrew and is etymologically related to the Semitic word for "power", (as in Gen 31:29, "I have the power (EL) to harm you") so the phrase could (and has been) translated as "Mighty is the God of Israel" as the name for the altar in context.
I also don't think ELYON is generally accepted by many legit scholars as referring to a pagan EL deity. You should probably do some more research on this issue. As EL is used in multiple meanings, in Hebrew when it is used to refer to God, it is used in what are called "construct forms" to put the meaning clear in context and to differentiate that this was ontologically ultimate God of the Jews - EL ELYON means "God the Most High" to emphasize His supremacy, power, etc. (as in Genesis 14:20) and sometimes simply as "The Most High" (like Num, 24:16) Other examples of construct forms in the Tanakh are EL OLAM, the Everlasting God or God Everlasting; EL ROI, The God Who Sees Me; EL GIBBOR, the Mighty God; EL DE'OT God the All-Knowing, EL HAGGADOL, The Great God or God the Great; EL HAKKAVOD, The God of Glory / Glorious God; IMMANUEL (God with us), EL HANNORA (God the Awesome / The Awesome God). EL KANNO (God the Jealous / The Jealous God), and many others. We also see EL incorporated into Hebrew names - Michael, Joel, Samuel, Gabriel, etc to connotae their closeness to God (especially in the case of the angels). It is even incorporated into Israel, "God Strives".
