How to merge generated objects in Unity?

Question

3D

I have a randomly generated maze that is created by building 4 walls and 1 floor in each cell. As a result, after generation, in the project I create a huge number of separate objects (4 walls and a floor), which eventually form the maze I need.

The problem is this: after generation, I want all these objects to be combined into one, so that it would not be a labyrinth made of many particles, but one whole maze, is it possible to do this?

Yes, documentation: https://docs.unity3d.com/ScriptReference/Mesh.Comb...
And there are many assets like https://www.assetstore.unity3d.com/en/#!/content/8748
