Add option to disable fields instead of hiding them

[mikesnoeren]

We often encounter scenarios where users need to choose between two inputs, for example; an Video file (asset) or a YouTube video (URL). This is how the conditions for that would look:

• Show Field X if Field Y has a value.
• Show Field Y if Field X has a value.

This setup causes the UI to become quite jittery as fields appear and disappear dynamically. It would be much more user-friendly to have an option to disable fields instead of completely hiding them, ensuring smoother interactions and a clearer interface.
