How to hide Salesforce Geolocation and other address fields from Marketo Sync

We're just setting up our initial sync between Marketo and Salesforce. Does anyone know where in Salesforce to change the Address fields that show up for a Profile? Address is it's own object in Salesforce and not listed with all of the other objects. I want to turn off the visibility for all of the geolocation fields etc. so they don't show up in Marketo but can't find where to hide their visibility for this Salesforce profile. Thanks!
