Is there a way to set the settings in Firefox's about:config page to "read only" so that addons cannot modify them?

I want to be able to lock in my tweaks to the settings in about:config so that addons and other third party applications cannot modify them without me first setting the permissions back to "read and write".

How did you determine addons and 3rd party apps were doing the changes?

WebExtensions can't modify pref that appear on the about:config page like was possible with Legacy extensions.

You can lock specific prefs to make it impossible to change them from within Firefox.

I have not diagnosed that, I just want a way to lock it down from other users changing it. These are custom settings on a publicly accessible (by employees) computer.
