How to set gzip variables/parameters

How can I set  these variables? Only 'gzip' looks to be available as class parameter. 
Can I set this with hieradata? 

gzip_min_length 10240;
gzip_http_version 1.1;
gzip_proxied expired no-cache no-store private auth;
gzip_types text/plain text/css text/xml text/javascript application/x-javascript application/xml;
gzip_disable "MSIE [1-6].";

Thanks for the help!
