It can.

In general nginx reloads configuration gracefully, so one option is just to write the config files with an application/script and do reloads.

Another way is to find appropriate module which allows dynamic upstream changes or for example there are modules which allow backends to be determined via dns (nginx itself can also use host based upstreams but in a more static way as the dns resolution is done only on startup and config reload (there are some hacks with variables but it's not as elegant)).

Next level would be to use Openresty and something like https://github.com/openresty/lua-nginx-module/#balancer_by_lua_block where you can do whatever comes into your mind (as far you learn to code Lua a bit).

Yes, the commercial version has inbuilt dynamic backend change feature.
