“location“ sets the location of the caption as well as the position
of the entire float. If you want to influence one, you'll also have
to specify the other, AFAIK. Which is a bit unfortunate since the
placement belongs in an environment and not the running text (it's a
style decision after all).

Take the following example:

\setupfloats [figure] [default=top]

\setupfloats [table]  [default=bottom]
%% \setupfloats [table]  [default=top]

\starttext
  \samplefile{knuth}

  \startplacefigure %% [location=top]  %% default
    \externalfigure
  \stopplacefigure

  %% Goal here: turn off the caption, not influence the default placement
  %% needs to be adapted when the global style changes
  %% \startplacefigure [location=none]     %% fails, messes up the placement
  \startplacefigure [location={top, none}] %% works
    \externalfigure
  \stopplacefigure

  %% Goal here: turn off the caption, not influence the default placement
  %% needs to be adapted when the global style is changed to “top”
  \startplacetable [location={bottom, none}]
    \externalfigure
  \stopplacetable
\stoptext

As far as I know there's no way to only turn off captions, so one
has to know the default placement value (which might be buried in an
environment file) and specify it again together with the “none”
option.

If you (or someone else) knows a way to disable the caption without
influencing the placement, I'm all ears.
