how to generate only cert and intermeidate file without root certificate authority

[simo222]

hi,

the acme.sh scirpt generates a ca file which contains the root and intermediate. well I don't need the root .

is there an option to generate ?

a) only the certificate and intermediate without root.

or

b) only the intermediates wihtout root ca.

according to rfc

https://www.rfc-editor.org/rfc/rfc5246#appendix-F.1.1
If the server is authenticated, its certificate message must provide a valid certificate chain leading to an acceptable certificate authority.

acme.sh generates a ca file however this one has a root inside .

server {
    listen 443 ssl;
    server_name myserver.domain.com ;

    ssl_certificate /etc/nginx/ssl/ myserver.domain.comm.crt;
    ssl_certificate_key /etc/nginx/ssl/myserver.domain.com.key;
    ssl_trusted_certificate /etc/nginx/ssl/ myserver.domain.com.ca.crt;

 location / {
          root /usr/share/nginx/html;
          index index.html;
      }
   } 

for /etc/nginx/ssl/ myserver.domain.com.ca.crt I want only the intermediates to be here. no root.

is this possible ?
just want to follow rfc.

no, the ca file only contains the intermediate certs, not including the root certs.
