magento2 – How to ignore the client attribute (created by a third-party extension) during Data MIgartion from M1 to M2?

I am currently working on the migration of data from Magneto 1 to Magento 2.

I found that some client attributes are created in Magento 1 by a third party extension.

I no longer use the above attributes in Magneto 2.

How to ignore the customer attribute and its data during data migration?
