Prohibitions in Latent Class

Is it possible to discover segments using a Latent Class analysis with prohibitions on some levels. I.e. Some levels are asked to place the product in a competitive environement but will never be used.

No.  In that case, I'd recommend using HB to estimate the utilities.  Export the HB utilities (via SMRT + Run Manager + Export) as zero-centered diffs (to normalize the utilities across respondents).  Then, drop the levels that shouldn't have an influence in the clustering.  Then, re-zero center the attributes that had levels dropped.  Then, submit those utilities to our CCEA package for cluster ensemble analysis (better than k-means clustering!).
