does fooocus support the command arg "--reserve-vram 2.0" or can i specify it to do so?

i was wondering if fooocus supported this flag or has a alternate way of limiting how much vram is reserved? when im using some other SD apps or trainers i can tell it to leave 2gigs of my 24gb to the system so the system dosent slow down and while generating images.
