There most likely is not (at the moment):
From the homepage:
It is a pure-VCL/CLX control, meaning it is not a wrapper for Microsoft Windows
controls and so no run-time library is required.
CLX or Component Library for Cross Platform is the cross-platform equivalent of the VCL – Borland’s widget library.
From Nakeymonkey – native controls for firemonkey
With the VCL, Borland never had to worry about all of this because they just wrote a wrapper around the Windows API Rich Edit control. So why didn’t Embarcadero do the same thing with Firemonkey? Because Firemonkey also needs to compile for OS X and the Windows API Rich Edit control doesn’t exist there.
