How do I downgrade my OS?

What is the best way to downgrade ones OS? For example, Big Sur to Catalina? Also, when I first did this, it changed the HD desktop icon to a slightly different one. The original just said Macintosh HD. The 2nd says, Macintosh HD-Data with an arrow at the bottom left corner. How do I get rid of that, and back to the proper Macintosh HD?
