I was looking for that too as a couple of the high end Rampage and Crosshair boards that just came out have them wired to a similar connector glued to and buried under the armor, though it looks a little bigger.

Another model of a ASUS board the battery is on the back of the USB port and 2 pin wire.
EDIT The 2nd link shows the battery the picture is the location and wire.
And again covered up with the heatsink. https://rog.asus.com/us/motherboards/rog-strix/rog-strix-z390-i-gaming-model/

And the manual for this model also fails to mention where the battery is. Although it does mention removing the battery if CLR_CMOS button fails to do its work. So it looks like those Asus boards indeed have battery under heatsink - which also means OP board is probably defective.

Unless maybe he leaves it unplugged so much the battery died? I mean still it shouldn't die that fast, and in the end even if it DID die it should still boot up and not require a hard CMOS reset via the rear button to boot.

FWIW I did the same with my old computers for years and the battery didn't run out. This computer is only 2 months old. OFC it could be an empty/faulty battery from the start but not very likely.

I've now written ASUS support. Let's see what they have to say about this.
