I can't stress it enough apparently: _all_ uBlox-8 have that feature.
Whether you can (easily) use it depends on whether the two pins are
not used for one of their alternate functions and if they're broken out
to be directly accessible.

I _think_ the uBlox-6 timing modules have it too, but I need to check
the documentation.  These may possibly not be implemented with hardware

Any other 8 series module with at least one of these two pins broken out
will suffice.
