On Windows you just install an extra MSI for Colemak, add it to the standard desktop build and you’re off (you use win-spacebar to switch to the new keyboard quickly when sitting at the keyboard).
On Mac you just switch to that layout (cannot remember the hotkey but there is one), no install required.
Linux likely has 15 different ways to do it and you just have to pick the easiest one for you.
You just need to have a chat with your boss. He’ll probably be happy to allow something that requires zero budget and ticks an extra “ergonomics” checkbox.
