Yes, that is exactly the function of this option, although I read that this only works if you're booting with fusee-primary, not with hekate fss0 method. So make sure to use that payload or chainload it through hekate until hekate gets fixed.So If I understand, if I put blank_prodinfo_emummc=1 in exosphere.ini this will make my switch as if it is in incognito mode ?
