BUUuuuuUuut… There are several different ways to make your own keycaps.
Silicon molds for resin pours. Sometimes even multistage pours for different parts of the cap.
3d printing/laser sintering is also an option and probably the easiest entry point into custom keycaps.
Clay/Ceramic can be sculpted to make caps.
You can order blank PCB caps in nearly every style of profile possible. You can then custom design your own legends and dye sublimate then onto the keys.
Some actual lunatic even went as far to manually load every blank Keycap into a CNC mill to carve out the letters so he could backfill it with a different material of his choice (I don’t remember the specifics).
Oh man… short answer is yes.

It’s a deeeeep rabbit hole.
