Create custom popup

What you want is a "Confirmation" type alert. 
https://support.sugarcrm.com/Documentation/Sugar_Developer/Sugar_Developer_Guide_11.0/User_Interface/Alerts/

You can add this in an on change event in the record view so that when the user changes that field you check the value, if it's Yes then you send the Alert.

The custom controllers you want to build are in:

custom/modules/<yourmodule>/clients/base/view/record/record.php 

and create view:

and custom/modules/<yourmodule>/clients/base/view/create/create.php

There are some examples of how to extend the record and create view controllers here:

If you are going to save regardless, then I would use a "Warning" with the option:

autoClose: false

However, if the purpose is to force someone to acknowledge and therefore not save unless they do so, the Confirmation seems to be the way to go.

You can manipulate the words on the button, and maybe even hide the "Cancel" button by customizing the alert if needed.

Else you will need to try and extend SugarAlerts to add your own type of button, but that will be a lot more work.

Depending on the ultimate business process it may or may not be worth doing that.
