How can import textures


Youth Team
Please can you help me, I have several problems for a patch that I am creating, ok, the first is that I have the FIFA 21 and it extracts all its textures but for example the adidas predator boots of the new generation have a different type of texture, and no How to import it, and I know it can be done because on YouTube there is a youtuber (Gamozola) that if I can import the textures of the new boots from 21 to 19 as well as balls, the other thing I need to know is how I can change the color Of the sources of the shirts, with the RBDM I know how to do it, but with the league kits, the cup and champions kits are another type of font and the color did not change, also how can I change the type of font, if someone could help me be infinitely grateful, I am creating something very great and I want to share it
