Can an RNAV approach have stepdown fixes on the final approach segment?
Yes.
When VNAV first came in they could only be an an LNAV-only IAP. Then,
quite a few years ago that was changed to permit them for LNAV minimums on
an LNAV/VNAV IAP.
An "advisory" guide slope could only be applied to a final approach segment
without stepdown fixes, or one in which the glide slope clears the
obstacle(s) by the required margin. I doubt that all LNAV-only approaches
have been TERPSed for that, especially those without VDPs.
