I'm not sure you can do that.

I think they mean the application icon that shows up as the current head of the player's character?

Line 44 in MinecraftClient.ini (AKA config file)

playerheadicon=true # Only works on Windows XP-8 or Windows 10 with old console
change playerheadicon=true to playerheadicon=false

If you are talking about in-game skin. if you are on a server with some plugin that restores skins you can't controll that.
