pdm config pypi.verify_ssl False is not working

[cvgaviao]

• I have searched the issue tracker and believe that this is not a duplicate.

Actual behavior

I'm trying to create a container image inside a linux server. I need to use my company's pypi server instead of the of the default one. But both RUN pdm config -v pypi.verify_ssl False or RUN pdm config pypi.url ${PYPI_URL} is giving me an error like the one below.
If I try to set pypi.verify_ssl first, it is trying to reach out the default pypi server, but it can't because it is blocked. And if I change the default pypi first, it doesn't work because it tries to validate a certificate.

Steps to reproduce

Block your own access to pypi.org and try to set any configuration

Expected behavior

Certificates not being verified and breaking the building...

Environment Information

# Paste the output of `pdm info && pdm info --env` below:

[frostming]

You need to first disable check_update or it will request pypi after the first pdm invocation:

pdm config check_update false
