You have several options (I extend my answer a bit due to the ongoing
discussion).

1. you want to read .wgetrc but want to explicitly set one or more
options for a special use case (disregarding what .wgetrc says for that
option.
Just use the option with the value you want, e.g. in your case use
either --convert-links=off or --no-convert-links.

2. create a special config file for your use case with all that special
settings, e.g. 'my.config' and specify it with --config=my.config.

3. Tell wget not to read a config file at all with --no-config.
Then you rely on wget's defaults which *might* change in future versions
(of course we wouldn't do so without a good reason).
[Sorry, that isn't documented as I just see - has to be fixed]

On production systems you want a stable behavior. So it might be good
not to rely on global config files that may be changed by you or someone
else (e.g. a system update might change /etc/wgetrc).
In this case either 2. or 3. seems a wise choice.
