What did you already try to solve it?
Search on this community articles and on the web. For information, it's the same for the stream page.

    Thank you

If you look at the end of the list of the list of options linked below, there are some for horizontal or vertical flip - only supported for the RPI camera.

That would flip it natively, rather than just in the display in OctoPrint.
