Hi Carolyn,
Those options that your are showing in your video cannot be toggled because they say they are "always required" (look at the paratheses after each option). These settings are *required* for DSpace to function. So, in the popup, we are *warning* users that DSpace requires this information, but they do no have the ability to toggle it off.
If, in your site, you enabled *optional* features like Google Analytics, then that would display a toggle that can be turned on or off.
So, it's important to be aware that not all toggles can be turned off. This is no different than other websites which sometimes will have required data that you cannot turn off.
