Exposed Unexpanded Group A Plastics

I am designing wet sprinkler system for a warehouse as per NFPA 13, commodity is exposed unexpanded group A plastic, ceiling height : 14 mt, storage height : 6 mt, storage arrangement: palletized. 

I can not use ESFR design since the ceiling height limitation is 12 mt in ESFR table.

As I see from the NFPA 13, there's no option for the CMDA design for this case either. I need to comply with NFPA 13. Waiting for the suggestions about possible solutions.
