Isn't that one of the things that was attributed to Abraham? That is - the focus on Yahweh as the only God rather than all the other gods out there at the time?
It's actually an interesting take on mono-vs poly-theism, that perhaps the other gods were in fact the fallen angels and/or Nephilim or demons or other spiritual beings or whatever. The Bible doesn't speak too much about those beings actually. And what the Bible does say, like in the examples with Moses and Elijah, is that those gods are indeed not 'omni-' in some aspect (omnipresent, omniscient, omnipotent, take your pick).
Well it mostly says their god is greater, period, without going into debates about omniness. But there are things.. for instance, the Bible lists Elohim as a name for the Biblical god. Yet... Elohim is a label that is applied to the children of El, which was the main god in several ancient Middle Eastern religions.
On the other hand wikipedia states that some scholars think that Yahweh might be shorthand for " "El who creates the hosts" in Phoenician.
And yet again, apparently old versions of Deuteronomy dont depict Yahweh even as the main god, but a child of El

When the Most High (’elyōn) gave to the nations their inheritance,
when he separated humanity,
he fixed the boundaries of the peoples
according to the number of divine beings.
For Yahweh's portion is his people,
Jacob his allotted heritage

Akhenaten, yes. And a big deal of the success in restoring the original order was Akhenaten's early death, leaving the kingdom in the hands of his priest-tutored and easily manipulated son, Tutankhaten
Well, more practically, Akhenaten was an iconoclast. His ban on the traditional religion might have been aimed at destroying the priest's of Amon power base, but it made him wildly impopular with the common folk (particularily in regards to the worship of the *other* gods, for what I've read. The element that made them really angry was the ban of the cult of Osiris)
