In this other example the problem is see more clear

Also it appear that bevel doesn't have enough strength to change completely the normal. like can be see in other softwares like modo

I quote @Brecht Van Lommel (brecht) who implement the node

@Brecht Van Lommel (brecht) I don't understand, that happens also without shadows.

Then have some reason that when I bake a simple bevel and load this happens in the normal?

In eevee

In cycles

Shadow terminator artifacts don't only happen with shadows, but also microfacet shadowing in the BSDF.

About normal map baking, bug reports require a .blend file and exact steps to reproduce.

I will create a new bug report for the normal map.
