Trying to Change a Variable in a single Blueprint

So I am making a game with 2 players. the 2 players are using the same Character Blueprint but I want to be able to customize them to make them different from each other at the start does anyone know any way to do this?

Two different character blueprints could be helpful if the character are significantly different.
You can select the character blueprint on start on spawn, in your game mode, for example.
There are many way to achieve this.
