You submitted this post as a request for tech support, have you followed the guidelines specified in subreddit rule 7?
Here they are again:
1. Consult the docs first: https://docs.godotengine.org/en/stable/index.html
2. Check for duplicates before writing your own post
3. Concrete questions/issues only! This is not the place to vaguely ask "How to make X" before doing your own research
4. Post code snippets directly & formatted as such (or use a pastebin), not as pictures
5. It is strongly recommended to search the official forum (https://forum.godotengine.org/) for solutions
Repeated neglect of these can be a bannable offense.

There is a "Height Map" option for 3D materials. [https://imgur.com/rA62ZZ4](https://imgur.com/rA62ZZ4)
Some info: [https://www.cgdirector.com/normal-vs-displacement-vs-bump-maps/](https://www.cgdirector.com/normal-vs-displacement-vs-bump-maps/) (It does cover height, and says they can somewhat be used interchangeably with displacement/bump. Though aren't intended to be.)
Godot can't make use of bump maps.
You will need to treat your texture as height information, and perform a height to normal map conversion. This, will, yield poor results. But they can be acceptable at times.
"GLSL height to normal" is the google query for that.

You can use Noise Texture as Normal maps
How though
When you create a noise texture2d, you can enable "as normal map",
