Unfortunately, there is no option to change the default behavior for the button.
However, you may want to disable buttons grouping via "Settings - Appearance & Behavior - Appearance | Window options -> Allow merging buttons on dialogs."
In this case, you will have a separate button for "Commit and Push".
As an option, you could use a keyboard shortcut (Ctrl+Alt+K on Windows).
