Try the custom filters for BP plugin – https://wordpress.org/extend/plugins/custom-profile-filters-for-buddypress/

Allows you / your users to be more prescriptive about what BP ‘auto-links’. Don’t think it will completely stop BP auto-linking some things – though you could, if you wished, tell the plugin to exclude ALL fields from being auto-linked.

You / users can also use the square brackets ‘[ ]’ in profile fields to specify words or phrases they do want linking.

The plugin’s pretty handy for specifying fields like web site / twitter that shouldn’t be auto-linked.
