Where is USB Restricted Mode controlled?

  *   The protection is enabled by default on Apple Silicon Macs.
  *   The enabled protection is to Ask for new Accessories, additional options include:
     *   Ask every time.
     *   Automatically when unlocked.
     *   Always.
  *   Asking for new accessories is the minimum protection that should be in place, though highly secure enterprises will want to mandate for permission each time.
  *   You can disable/enable the setting in System Settings>Security & Privacy>Security.
  *   Configuring an accessibility Switch Control sets the policy to always allow accessory use.
  *   Approved devices can connect to a locked Mac for up to three days.

What about updates? Apple explains that accessories attached during software update from prior versions of macOS are allowed automatically. New accessories attached prior to rebooting the Mac might work, but won’t be remembered until connected to an unlocked Mac and explicitly approved.
