How could I prevent duplicate field values in Liferay form

Hi everyone,

I'm using Liferay DXP 7.2 forms and I need to add custom validation on a field to prevent end-user (guest) to insert a duplicate value (already inserted by any anonymous user before), could anyone support me on how to handle this.
