There's nothing clever about the kobopatch which enables kerning/ligatures in kepubs. All it does is make sure every kepub on the device can access the following CSS style when displaying text:
Code:
body{text-rendering:optimizeLegibility}
If you don't want to use kobopatch to do it, other methods exist. Only you can decide which is "best" (
or least worst 
) for you. The patch has the benefit that it should work equally well in kepubs delivered directly from the Kobo store and kepubs you sideload (via calibre or manually).
Other methods need to find a way to add the above CSS style to the CSS file(s) in each book. Here are 3 methods which should work, with varying pros/cons. Take your pick and experiment:
- Use the 'Modify CSS' option in the calibre Kobo driver (KoboTouch or KoboTouchExtended) to add it during the calibre Send-to-Device process. More details here.
- Use calibre's Convert > Look&Feel Styling > Extra CSS option to add it during conversion.
- Manually add it to each book using an epub editor (calibre or Sigil).
