sure

you just read how it works in here:
https://httpd.apache.org/docs/2.4/mod/mod_proxy_fcgi.html


then in apache `frontend` vhost config you add something like this:

    <VirtualHost 1.2.3.4:443>
        ServerName example.com
        ServerAlias www.example.com
    
        DocumentRoot /home/example/public_html/ 

    <IfModule proxy_fcgi_module>
        <FilesMatch \.(phtml|php)$>
                SetHandler "proxy:fcgi://127.0.0.1:9000"
        </FilesMatch>
    </IfModule>


then in apache `backend` vhost config you add something like this:

      <VirtualHost 4.3.2.1:443>
        ServerName admin.example.com
    
        DocumentRoot /home/example/public_html/

    <IfModule proxy_fcgi_module>
        <FilesMatch \.(phtml|php)$>
                SetHandler "proxy:fcgi://127.0.0.1:9001"
        </FilesMatch>
    </IfModule>
