Start by reading the recipe and see what variables or PACKAGECONFIG
options it uses to derive the configure options.

If there's no PACKAGECONFIG option to control the feature then
(assuming it's an autotools recipe - which again you need to read the
recipe to determine) you can add additional options to EXTRA_OECONF.

Once you know what variable you are trying to change (e.g. appending
to PACKAGECONFIG, EXTRA_OECONF, etc) then there are many ways you can
do so. Editing the recipe, creating a .bbappend for the recipe or
setting via local.conf (which case you'll need to use a recipe
specific over-ride since local.conf is a global config file and you
only want your change to apply to one particular recipe) would all
work.

The basic advice though is to try to understand the change you need to
make a how to make it by reading documentation or existing recipes etc
and trying to figure out how and why they work. Trial and error is not
a good way to try to learn OE.
