how to enable http2 for two server hosted on the same IP

[meteor8488]

Hi All,

If I use 

server {
	listen       443  accept_filter=dataready ssl http2;
	}
server {
	listen  443 http2 sndbuf=512k;
	}

I'll get error
 duplicate listen options for 0.0.0.0:443

I know it's caused by http2 in server 2. But how can I enable http2 on two
servers?
