Those config directives (corrected) will inherit to any "location" which
does not have a "proxy_http_version" directive or a "proxy_set_header"
directive, respectively. (Assuming that neither are set at "server"
level either.)

Can you show the config that does not react the way that you want it to?

If you get the upstream (proxy_pass) server to "echo" the incoming
request, can you see what http version and http headers are sent by nginx?

Directive inheritance follows the rules, or there is a bug. If these two
settings mean that keep-alive works for you, then you must make sure
that these two settings are in, or inherited into, each location that
you care about.
