They can be ran on 32GB with 8GB VRAM. I don't think these will be on 16GB for a while. (35B MoE)
But this could be done with just llama-server normally. I don't use any special command, just ensure that it's using the GPU. I've found the default fitting to be good.
From memory:
llama-server -m models/Qwen3.6-35B-A3B-UD-Q4_K_XL.gguf -fa on -c 128000
