Allow specifying a local file path on the VM to use the logo directly.

Hey,

You could upload your image on the defguard core server, and add this configuration to nginx:

        location = /logo.svg {
                root /var/www/html;
        }

Then the login logo url in defguard settings would be /logo.svg
