Keep local files

Hi,

I have a multisite installation of WP. I have define all the variables below in the wp-config.php.

MICROSOFT_AZURE_ACCOUNT_NAME – Account Name
MICROSOFT_AZURE_ACCOUNT_KEY – Account Primary Access Key
MICROSOFT_AZURE_CONTAINER – Azure Blob Container
MICROSOFT_AZURE_CNAME – Domain: must start with http(s)://
MICROSOFT_AZURE_USE_FOR_DEFAULT_UPLOAD – boolean (default false)

I would like to avoid content creators checking the “Keep local files” check box, on their specific site.

Is there a variable that can be defined for that like the ones above? Is there another way to disable the “Keep local files” check box. I want to ensure every asset uploaded goes to the Azure blob container specified in the variable MICROSOFT_AZURE_CONTAINER.

Any help will be greatly appreciated.

Thank you.
