support cuda for flatpak

currently we don’t have cuda-computing capability on flatpak. it’s a very anticipated missing feature on flatpak (see https://github.com/flathub/org.blender.Blender/issues/8). many apps (include but not limited to blender) require cuda support that currently not available, some of them can’t even run from what i heard of. so any help would be very apreciated…
