I am hoping for some guidance on how to best address disabling the multi-user functionality altogether so that a guest user/session cannot be initiated. Quick Internet search indicates it's as simple as merely editing the build.prop file in /system as below:
Multi Users
fw.max_users=1
fw.show_multiuserui=0
fw.show_hidden_users=0
fw.power_user_switcher=0
My conundrum is how to best access the build.prop file. The tried and trued suggestions don't seem to apply to GrapheneOS build.
Any nudge in the right direction is greatly appreciated.
Thanks in advance.
