Yes, you can. Specific ACF fields can be ignored from the Link Whisper settings. To ignore an ACF field, go to the Link Whisper settings and open the “Content Ignoring” tab.

Inside the tab, near the bottom of the page, is the “ACF Fields to be Ignored” field. Enter the “field name” of the ACF field you want to ignore. If you want to ignore multiple fields, enter each field name on its own line in the field.
