SetSiteStatus

You can use environment variables for site statuses though. First add a variable to your .env file or wherever else 
environment variables are set – for example something like SITE_FOOBAR_STATUS=0 (it can be named anything). Then open the 
site's settings page in the CP, and enter/select that variable with a $ prefix in the site's "Status" field.


That way, the environment variable reference will be saved to project config, and not the actual value, which means you can 
set that variable to either 1 or 0 to enable or disable the site across different environments.
