You cannot because its illegal to do so.
To mod with a USB stick, first, you need to format the USB drive to a compatible file system, such as FAT32. Next, download the mod files and transfer them to the USB stick. Insert the USB into your gaming console or PC, then launch the game or mod manager, and follow the specific instructions to load the mod from the USB. Always ensure that the mods are compatible with your game version to avoid issues.
