Changing iPhone setting for wired accessories for security reasons

That is a known bug and Apple is aware and will surely release an update in the future, which fixes it. I'm in the US and have the same on my iPhone 17 Pro Max. I don't have any managed software on my device, but the setting can't be changed. I spoke with Apple and they acknowledge this is a known bug.

.... Clicking on that takes you to the next page, which is grayed out and "This setting is managed by your organization and cannot be changed." is checked. What organization? This is a private phone not related to any organization. Anyone have an answer?

That is a bug, mainly it seems in the regions of UK, Sweden , maybe some others

We are not allowed to speculate, but I advise waiting for ios26.2, you may be pleasantly surprised.
