Вы можете попробовать это:
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
PROXY = "23.23.23.23:3128" # IP:PORT or HOST:PORT
capabilities = dict(DesiredCapabilities.CHROME)
capabilities['proxy'] = {'proxyType': 'MANUAL','httpProxy': '23.23.23.23:3128','ftpProxy': '23.23.23.23:3128','sslProxy': '23.23.23.23:3128','noProxy': '','class': "org.openqa.selenium.Proxy",'autodetect': False}
chrome_options = Options()
chrome_options.add_argument("--disable-notifications")
chrome_options.add_argument('--no-sandbox')
chrome_options.add_argument('--verbose')
chrome_options.add_argument('--disable-gpu')
chrome_options.add_argument('--disable-software-rasterizer')
chrome_options.add_argument('--headless')
chrome = webdriver.Chrome('./chromedriver',options=chrome_options) #<----- I used './chromedriver' to set a PATH
chrome.get("http://whatismyipaddress.com")
