Disable console output of webdriver using selenium in python

I'm trying to run a python program that uses Selenium and Chrome to analyze data from some websites. The problem I'm having is that either Selenium or the Webdriver is flooding the console with output I don't care about and making it difficult to view my programs output. I've read many other threads about this with various driver options, but nothing seems to work. The best these options do is remove this:

DevTools listening on ws://127.0.0.1:54429/devtools/browser/bbc7bc4a-bdf2-43a3-9fd4-c94dd9113aea

But all of these remain:

Is there any way to get these removed as well? Here is my setup for the webdriver (I've tried enabling/disabling many combinations of these options in case something is conflicting, but that didn't help):

from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities

options = webdriver.ChromeOptions()
options.binary_location = chrome_path
options.add_experimental_option('excludeSwitches', ['enable-logging'])
options.add_argument("--headless")
options.add_argument("--log-level=3")
options.add_argument("--window-size=1400x1080")
options.add_argument("--mute-audio")
options.add_argument("--no-sandbox")
options.add_argument("--disable-dev-shm-usage")
options.add_argument('--disable-extensions')
options.add_argument('--disable-gpu')

capa = DesiredCapabilities.CHROME
capa["pageLoadStrategy"] = "none"

browser = webdriver.Chrome(chrome_options=options,
                                desired_capabilities=capa,
                                executable_path=chromedriver_path)

Here are my versions:

python: 3.8.2
selenium: 3.141.0
chrome: 83.0.4103.61
chromedriver: 83.0.4103.39

this worked for me chrome_options.add_argument("--log-level=3")

another answer suggested using "--log-level=OFF" however this didn't seem to work for me

You can send all logs to the void, as described in this question

import os

# Let python handle it
driver = webdriver.Chrome(service_log_path=os.devnull)
# The proper null device option for Windows
driver = webdriver.Chrome(service_log_path='NUL')

, or use the less documented 'silent mode' explained here

options.add_argument("--log-level=OFF")

Hope one of these helps!
