Add Trusted Certificate On Docker Desktop Linux VM

I’m trying to use Docker Desktop behind a corporate proxy. I pointed my security team to the Docker knowledge base article about HTTPS_PROXY, as well another article.

The second article proposed adding a trusted certificate onto the Linux docker host, and security provided me a proxy certificate that I would add. However, I’m not sure what’s the best way to get into my Moby Linux VM and add this certificate. I tried following this article using nsenter, but I ended up with only read-only permissions it seems:

So, I’m at a loss for the best for to do this. Linux is not my strong suit. It would be nice if Docker Desktop had something in the UI setting for adding this.
