Restriction of LOV before particular date through form personalization.

Hi All,

Can anyone guide me how can we stop the users from selecting a check box (apply/unapply check box) in apply/unapply prepayments form for some particular LOV as per requirement.

What personalizations can be recommended from below:

1. Creating a pkg according to the needed conditions and throwing an error.
2. Can we do any personalization not to select the check box.
3. Should we disable the LOV that we don't require.
4. or Can we do any personalization not to select the record or prevent the form from saving.

Which one from the above can exactly work for my requirement.
