How can I have a Skybox object that works as background all around my scene but also have a HDRi or Sun to produce ambient light?. In my current setup the Skybox blocks the HDRi or Sun.

If you are using a mesh for the "skybox", all you need to do is make the material visible to camera, but transparent for all other rays. A light path node is used as mix factor in a mix shader node for this.
Then use a normal environment texture in the world.
If you have a real skybox texture then use it on the world as enviroment along with another texture to light the scene, and use a light path node to control the visibility. The camera will see one background, but the scene will be lit by the other.

$\begingroup$ Thanks for the answer, but my Skybox isn't a background usable with Environment texture. It's a mesh, with different texture and layer (clouds and other stuff animated). I just want to exclude this object from blocking light. My question title got edited and doesn't mean the same thing as what i'm asking now $\endgroup$– Melio550Commented Dec 29, 2020 at 7:39
