Is there ability to disable some default fields?

Hi Support team,

In our project, we do not use some default fields in test cases/cycles. Such as Objective, Iteration, Planned start/end date, etc.

Since we do not use them, it would be very convenient to disable these fields to avoid confusion from the users' side.

Could you please advise if there is the ability to disable such fields? If so, how to do that? In Zephyr config on UI there are only custom fields, but nothing about default fields.

Thanks in advance,

Anton
