Like I said, I literally have 0 usb settings available by going into the submenus. Including "Connected devices > USB Preferences" and "Network and Internet > Hotspot and tethering > Usb tethering". The submenu "USb preferences doesn't exist.
I'm not sure if the first one really is a submenu or just a dialogue which usually pops up when you connect the device to e.g. a computer. If I search for it like you do, it indeed shows up in results as Connected devices> USB preferences.
Maybe (misleadingly) that appears to be a link to a sub menu while in reality it's not?
The second one (USB tethering) is located under Settimgs> Network & imternet> Hotspot & tethering> USB tethering
. It's grayed out if you have not connected a corresponding device via USB.
Where to find exploit protection settings treequell already mentioned.
Have you tried to change the settings while being connected via USB to a computer or is your question just about where to find rhe settings you mentioned?
