Reskinning and Trimming
This system ships deliberately over-supplied so you can cut rather than write.
Trim the Gear. If your game is a fantasy game, delete Equipment/Modern, Equipment/Cyberpunk and Equipment/Sci-Fi. Nothing references them and the slots on the character sheet will simply offer fewer options.
Trim the Abilities. A game with no magic in it should not have a Magic Abilities folder. Delete it and the character sheet tab sits empty.
Rename everything. The four Ability categories are Tech, Magic, Physical and General because those are useful defaults, not because the system needs them. Rename the file types if your world calls them something else.
Adjust the slots if your world needs it. The nine worn slots live on the character type as filtered reference fields and on the gear type as a slot enum. Adding a slot means adding a value to that enum and a matching field to the sheet.
Keep the Rules folder consistent with what you cut. If you delete magic, edit the Abilities rule so it does not promise four categories.
