Primary and Secondary Network in configuration.yaml

Hi, I am new to hassio.

I want to have primary and secondary networks for connection to the web interface with wifi as backup.

is the following valid in configuration.yaml, the check config appears to think it is but I believe it just checks the structure of the yaml as you can put rubbish in as long as it follows the correct structure.

network:
    interface: enp2s0
        enabled:true
        method:auto       
        Primary:true
        secondary:false 

    interface: wlp2s3u1
        enabled:true
        method:auto
        primary:false
        secondary:true

I don’t think so. Supervisor → System, next to ip address click change
