It appears you can set in policies whether or not an extension is
 allowed in private browsing:
<https://mozilla.github.io/policy-templates/#extensionsettings>
See 'private_browsing' - boolean

Whether that removes the setting from the options, or disables
 changing it, you'd have to test.

And it depends whether you /want/ to force it into private browsing.
