[🐛 Bug]: RemoteConnection.set_certificate_bundle_path set as None does NOT work

[limuyuan]

What happened?

Same issue as #13931. Error:

MaxRetryError(_pool, url, reason) from reason  # type: ignore[arg-type]
urllib3.exceptions.MaxRetryError: HTTPSConnectionPool(host='internal-xxx.elb.amazonaws.com', port=443): Max retries exceeded with url: /selenium/wd/hub/session (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1129)')))

I was using a self-signed certificate for my website. I set the certificate bulde path to None but the certificate error still disp;layed.

How can we reproduce the issue?

from selenium import webdriver
from selenium.webdriver.remote.remote_connection import RemoteConnection

rc = RemoteConnection(url, keep_alive=True)
rc.set_certificate_bundle_path(None)
rc.set_timeout(600)
driver = webdriver.Remote(command_executor=rc, options=options)
