How to change system font on MacBook Pro M1?

Am I able to change my font on my MacBook Pro M1 running Version 26.2 (25C56)? I tried an app called TinkerTool, but that was no help. Would anyone be able to assist?


P.S - I don't know if this is even possible, since everything I looked up on google was no help. I thought that I would turn to the professional people.

MacBook Pro (M1 Pro, 2021)

macOS system fonts are fixed, you do not have r/w permission to make changes there.

macOS primarily uses SF Pro (San Francisco Pro)


Within Individual apps maybe a different story...
