oh, I only know GMS2 and Construct 2/3, so I can't help you with Unity unfortunately.

I found this guide with a quick search, I hope it can be useful: https://pavcreations.com/pixel-perfect-fonts-in-unity-the-practical-guide/

You can use Text Mesh Pro. It depends on what your gonna do but Just download TMP then use the Font Converter to be able to use it.
