I cant access or edit a texture/shader for my provided model., I cant access any of the settings of the shader as it is grayed out.

I was provided some models and textures for a walk through project for an independent course I’m taking. I have looked through many question regarding this problem but none have lead me to the right answer. When i try to access or edit my shader inspector on any model it wont let me edit or access them. However on the lecture I was watching the professor was able to edit it as simple as that. Does any one have any idea how to fix this. Thank you.
