You're going to have to back it up with raw data DME by tuning in the TCH VOR.

When the GPS displayed waypoint DME counts down and reads 0.0 passing over KERNN (FAF), the raw data VOR DME will read 10.2. The approach plate does say "DME required".

We always back up FMS/GPS waypoints with raw data DME if required and depicted on the approach chart.
