Hi @SivajiM16634140

My understanding it is not possible to call in Data Transform,

Edit validate rules are defined on Properties in Advanced Tab there is option Use validate , and not on Data Transform or flow actions. Edit validate rules are used for client-side validation, which means that the value users enter is validated immediately without referencing the server. Validation occurs when users make a change to the entered value. To apply an edit validate rule to a property, reference the edit evaluate rule on the Advanced tab of the property rule form, in the Use validate field. The following example shows a property rule for capturing a postal code, with an edit validate rule applied to verify that entered values match the US ZIP Code format.

Note: You can call Edit validate rule in Activities, by using the Property-Validate method. 

Please refer below articles, 

Role of edit validate rules in data validation and About Edit Validate rules

Thanks,
