box configure:settings --cert or reading of Window ENV REQUESTS_CA_BUNDLE

Is your feature request related to a problem? Please describe.

Box CLI from Box Command Line Interface Installer-win10-x64.msi has no issues at work going through Proxy and SSL Certs.
Box Python SDK, Box CLI - only supports Proxy: in Python boxsdk.config import Proxy.
My notes on how to get requests.get() working on Windows 10 with Proxies, Certificate as a .pem file in Python
Two ways to do this:
A: requests.get( URL, proxy=, verify= path to .perm file )
B. Set the Environment Variables: HTTPS_PROXY  REQUESTS_CA_BUNDLE then requests.get( URL ).
I had to use method B because Python boxsdk only has Proxy, no way to bring in a Certificate - from boxsdk.config import Proxy.
import os
os.environ['HTTPS_PROXY'] = proxy [Proxy as string]
os.environ['REQUESTS_CA_BUNDLE'] = CombinedPem [Path to .pem file as string]

Describe the solution you'd like

Add a CERT option to import a .pem Certificate file.
box configure:settings --cert

Example, just added: Box CLI adds proxy support Cristiano Betta Aug 24
box configure:settings
--proxy-url=socks://your.proxy.server.com:1080
--proxy-username=YOUR_USERNAME
--proxy-password=YOUR_PASSWORD

Describe alternatives you've considered

Box Python SDK is one option.
Box CLI 1.4 works "out of the box" - Box Command Line Interface Installer-win10-x64.msi
Opened a Support Case with Box - they confirmed that they don't have an unpublished work-around.
I found earlier: Error in Box CLI: self signed certificate in certificate chain https://support.box.com/hc/en-us/community/posts/360049157234-Error-in-Box-CLI-self-signed-certificate-in-certificate-chain
