Turning off devices

Gnome disk manager has a “disable” device function.
I don’t like GNOME, but why do they have this function and we don’t?
But there is a completely unnecessary function in the menu (after installing KDE manager) - disk formatting? Are you constantly asking me to format the disk? Why?
But “disable device” - NO.

When removing the USB device, it continues to light up. And the USB HDD also does not turn off everything normally.

It would be good to add disk disconnection after removing the disk.
