Hi! Yes, you can, but you will have to do it your own way. All the textures I used come with the assets, and if you're familiar with Blender, you can open the project .blend file (comes with assets-only version) and look at the water shader I made and try to replicate it in Unity. It's a little more advanced, but you can also do something simple with it. There's like 11 different water textures to play around with, so there's a lot you can do!
