To show the page without CSS, to make page loading faster you can disable the Preferences used for storing the default values for the individual content settings using the following solution:

• Code Block:

  from selenium import webdriver
  
  options = webdriver.ChromeOptions()
  prefs = {'profile.default_content_setting_values': {'cookies': 2, 'images': 2, 'javascript': 2, 
                              'plugins': 2, 'popups': 2, 'geolocation': 2, 
                              'notifications': 2, 'auto_select_certificate': 2, 'fullscreen': 2, 
                              'mouselock': 2, 'mixed_script': 2, 'media_stream': 2, 
                              'media_stream_mic': 2, 'media_stream_camera': 2, 'protocol_handlers': 2, 
                              'ppapi_broker': 2, 'automatic_downloads': 2, 'midi_sysex': 2, 
                              'push_messaging': 2, 'ssl_cert_decisions': 2, 'metro_switch_to_desktop': 2, 
                              'protected_media_identifier': 2, 'app_banner': 2, 'site_engagement': 2, 
                              'durable_storage': 2}}
  options.add_experimental_option('prefs', prefs)
  options.add_argument("start-maximized")
  options.add_argument("disable-infobars")
  options.add_argument("--disable-extensions")
  driver = webdriver.Chrome(chrome_options=options, executable_path=r'C:\Utility\BrowserDrivers\chromedriver.exe')
  driver.get('https://play.google.com/store')
  

• Browser Snapshot:

Unfortunately, it is not possible in Chrome.

ChromeDriver disable rendering and CSS

Chrome/chromedriver cannot run headless without some virtual screen like Xserver, and it can't not-render the html and css.

Exhaustive list of all options that are allowed:

profile.default_content_setting_values:

cookies,
images,
javascript,
plugins,
popups,
geolocation,
notifications,
auto_select_certificate,
fullscreen,
mouselock,
mixed_script,
media_stream,
media_stream_mic,
media_stream_camera,
protocol_handlers,
ppapi_broker,
automatic_downloads,
midi_sysex,
push_messaging,
ssl_cert_decisions,
metro_switch_to_desktop,
protected_media_identifier,
app_banner,
site_engagement,
durable_storage

I've been wondering the same thing, and came across this (credit to https://www.scrapehero.com/how-to-increase-web-scraping-speed-using-puppeteer/)

It's not selenium, but in Pyppeteer you can intercept and modify network requests made by the page using setRequestInterception. This would allow you to intercept and abort css network requests, which would avoid downloading css files and their subsequent rendering.
