This document explains how to achieve this requirement.
Architecture
The following steps explain in detail,
Step 1:
Open your dialog page in Oracle Apex. Then the right side of the property palette, scroll down to the Dialog section and add the following code to the Attribute property:
closeOnEscape:false
If you run the page now you can see, the ESC key has been disabled and prevention of dialog Page close has been achieved.
Step 2:
Open the parent page from where you are opening the dialog page and add the following CSS code in the Inline CSS property section:
.no-close .ui-dialog-titlebar-close { display: none;}
Save the changes to the parent page.
Now open your dialog page and in the Dialog property section add the no-close class in the CSS Classes property.
