I looked in the UEFI settings and didn't see a slider for turning the card slot off.
Is there a setting somewhere to disable the hardware so the card slot will not work?
Not as secure as having it fully disabled in the UEFI settings.
I find it quite odd that there isn't a slider to disable the SD card along with the other hardware settings like cameras and Bluetooth you can disable with in the UEFI settings
Truly a bizarre omission.
