[Qlustar-General] how to add GRES resources to qluster manually

Hi, In my cluster I have two exotic IBM Power servers with NVIDIA cards. I succeded install Ubuntu 18.04 and make slurm working qith qlustar 11 server, but for NVIDIA cards to manage I cannot find any way to add manually those resources to global slurm config (gres.conf is managed by qlustar and no way to add something manually).
