Enabling Strata (Substrate) with 5.1 Caustics branch

Getting several Lumen shader compile errors when I try and enable Strata materials in Project Settings.
Can anyone confirm whether Strata can be made to work?
Most seem to be related to LumenReflectionHardwareRayTracing so will try disabling and repost if successful.

Substrate materials are still “released as Experimental in UE 5.2” even though they alredy came as “Strata” in 5.1. From what I hear internally and what I can share is that you should not expect it to work “out of the box”.

If you find some valid workarounds or solutions, we are all ears!
