Yes, you can have different listening sockets configured with different 
options, e.g.:

    server {
        listen <ip1>:443 ssl http2;
        ...
    }

    server {
        listen <ip2>:443 ssl; # no http2 here
        ...
    }

Note though that you have to direct clients to these different IP 
addresses, so using private IPs won't work.  Rather, you have to 
use different public IPs.
