How to remove button from the system toolbar?

Can you tell me if this bottom system toolbar can be removed?

I need to remove this system button for a particular field. How can I do this?

Solution

I think this is fine-tuning and would be difficult to apply to a specific field. In particular, remove the refresh button. It is not very clear the relevancy and frequency of such a setting. But if you really need to implement it, I would use css. It would be easier to apply to a form. Maybe there are other options, but that's up to the developers. I don't know
