Perhaps something like:

# http level

map $http_accept $my_upstream {
   default misc_upstream;
   ~text/html html_upstream;
   
}

upstream misc_upstream {
    server 127.0.0.1:8080;     
}

upstream html_upstream {
    server 127.0.0.1:8088;     
}

# server level

location / {
    #... your stuff
    proxy_pass http://$my_upstream;
}
