How to save only specific VO object changes in database by ignoring other VO changes

HI COmmunity

I am currently using JDEV 12.2.1.3.0 and I want a solution for below scenario

I have one JSFF in which I have a form with some check boxes and a button to show a popup to show a table that has a submit button in which I am executing a commit to save changes done to that table. Here, both the form and the table are backed by an EO, and whenever a user changes data in the form, for example, a check box is checked, and after that change, the user opens that popup and does some changes and submits those table changes using the submit button, but this submit is also saving
