@jiangxiaoqiang I think the intended use is to facilitate keeping a driver up to date and patch it. The intended use, that should be clearer in the documentation, is to pass the argument driver_executable_path when initializing the Chrome() class, like so:
driver = uc.Chrome(driver_executable_path="/home/<your_username>/.local/share/undetected_chromedriver/undetected_chromedriver")
So, I would recommend using just simple Chrome() once in a while, let the script do it's thing, and then use the above option so it doesn't download-and-patch everytime.
