Form Calculation Widget: Calculation Field needs to be Read Only by default

How can I make the calculation field widget Read only? I have added a calculation field "Points accumulated" on form "nursing CAP Documentation submission form" but I could not find the settings to make it read only?

Here's a visual guide. 

This is performed in the form calculation widget settings

I have also escalated this as a feature request so our developers would consider making this widget read-only by default since this field is designed to calculate field values and I think it shouldn't be editable.

Thank you but I do not see those options on my screen. See my screenshot below

Click the ... 3 dots button to view those options.
