Question Set Additional nginx directives from command line

[assist bss]

I need to programmatically set nginx additional directive from command line (command line utilities or bash).

Watching at documentation I can't figure out how to achieve my goal.

For example for php settings is possible to pass a file containing additional setting, but I can't find a similar option related to nginx.

plesk bin subscription --update-web-server-settings example.com -nginx-???

Am I missing the proper option?

If It's not possible from command line utilities could someone provide an alternative to edit additional nginx directives for a subscription from bash?

-----------------------

Found this guide useful: update nginx directives for several domains

In my case I just need to do:

echo "

location ~ /.well-known {
allow all;
}" >> /var/www/vhosts/system/$dominio/conf/vhost_nginx.conf
plesk sbin httpdmng --reconfigure-domain $dominio
​

I don't know if there is a better way but works for me.
