If by "files" you mean "folders", and by homepage you mean homescreen, then you cannot.
The folder backgrounds are technically slightly translucent / frosted, and will show the blurred color of the wallpaper section behind them, unless Reduce Transparency is turned on in Settings ➜ Accessibility ➜ Display & Font Size, in which case, they will just be gray.
