How can I override Label Studio’s CSP_CONNECT_SRC in Docker to allow loading CSVs from a custom domain?

I want to load CSV files hosted at https://my.custom.domain/data.csv into Label Studio, but when I point to that URL in the UI I get this console error:

Refused to connect to 'https://my.custom.domain/data.csv' 
because it violates the following Content Security Policy directive: 
"connect-src 'self' 'report-sample'".

When I add my domain to the CSP_CONNECT_SRC list in “label_studio/core/settings/base.py” it works, but how can I edit this list in docker?

Thank you

Share your setup!

What version of Label Studio you’re using (for example, 1.10.0).
1.18.0
