REF: UEFI_Spec_2_10_Aug29.pdf page 1695. In 35.5.4 EFI_HII_CONFIG_ACCESS_PROTOCOL.CallBack(): If the callback function returns with the ActionRequest set to _QUESTION_APPLY, then the Forms Browser will write the current modified question value on the selected form to storage.
Update the SetupBrowserDxe, if callback function return EFI_BROWSER_ACTION_REQUEST_QUESTION_APPLY, then call SetQuestionValue with GetSetValueWithHiiDriver to apply the change immediately.
