Strange lowpoly shading artifacts when rendering game character

Strange lowpoly shading artifacts when rendering.

This is not a smoothing group problem nor bake cause there is no hard edges on these places and this doesn't appear on draft mode or on marmoest viewer. so it's a rendering lighting problem. There is seems on some of these places but all the wires are stacked and this doesn'tappear everywhere and it also appears where there is no seems

Here is the topology (triangulating fixed some of these issues on the body but nothing changed on the wire)

Has someone already encountered that issue and were you able to fix it ?

And no there is no artifacts on the hands and I am going to rework them anyway.

look :

draft

full quality

look like it completely ignore the normal map.

This is an issue I have pretty consistently with toolbag. When I run into this issue (which I do every time I use it) here are the steps I try:

turn your lights off and on until you figure out which light is casting that particular shadow, and increase the diameter of that light in the light settings under 'Area/Shape' until the shadow softens.
If that isn't enough, try slightly adjusting the position of the light.
If even that is not enough, try subdividing the model in Regular mode in the model properties.
As a hail mary and at the risk of losing the model's form, try subdividing in catmull-clark mode instead.
In the event that the hard shadow persists after all this, just sub in the high-poly version, or tell yourself that you're going for a wabi-sabi aesthetic.
