The way you’re drawing probably effects this, I’ve had better luck attacking the draw from the bottom of the grip up, kind of like what Gabe White does, when working from a lower ride height. This seems to put my knuckles behind the belt line earlier.
It’ll probably be easier to just angle the faceplate of the enigma down though. That’ll give you more clearance between the grip and faceplate, you may need to change which mounting holes you use to keep the same pressures on the holster though.

I've seen a lot of pictures of taped up enigmas using moleskin, gaf, and friction tape. There are some posts on the phlster FB group about your exact issue.
No matter which Enigma/holster/mount points combo you have there is usually a bit of play in the mount points that allow you to slightly tilt the grip away from the Enigma wing... It doesn't take much to create additional clearance. Loosen your mounting bolts and experiment a little.
