Not possible.

That would work only if there are no other Jack clients in the
signal path of the export. In theory it should be possible to
isolate only those that actually are connected somehow to Ardour,
and let the rest run normally, but that is not how it works.

That seems impossible.

If any of the sources required for the export is not a Jack client
or not synced to Ardour or not capable of running in freewheeling
mode, you simply can't expect export to work.

No, you could still have processing in other Jack clients which
are connected to Ardour (i.e. external inserts rather than plugins).
A common example would be a mastering processer such as Jamin.
