how to enable ONLY dGPU (not "hybrid mode")

hello, i use both mint and fedora.

-in mint i can choose between Just nvidia gpu(dGPU) hybrid (dGPU+iGPU depending on workload) or just intel gpu(iGPU)

-but on bazzite the supergfx options only shows hybrid and iGPU but doesnt show the only Nvidia gpu

how can i fix this?
