No, you can't.

Usually there's a good reason for BEX queries not to use the parallel query feature.
That reason is: parallel query turns your multi-user database into a single-user query machine.
This single sql session will aquire way more resources than a standard query - eventually blocking other activities.
In order to speed up your BEX query better check the execution plan and figure out what makes the query too slow.
Open a support message for it if you cannot do this yourself - there are quite some bugs around (even with Oracle 10.2.0.4) that lead to bad quey performance.
Of course - the first things to check would be to install the current Oracle patchset, patches and setup the parameters correctly. More than 90% of all performance support messages are solved just by that!
