To replace the textures of the default tabaxi subrace with the ocelot or void cat textures, just move one of the folders above to your BG3 Data folder, usually located at: C:\Program Files (x86)\Steam\steamapps\common\Baldurs Gate 3\Data, then rename the folder to just "Generated".  Note that you'll need to install the most recent version of the tabaxi mod as well for the retexture to work.
