Thanks Ravi, I appreciate your help. That worked perfectly.

Ravi,
That works perfectly.
And is exactly what I wanted to achieve.
I appreciate your help very much indeed.
Thankyou sir!

Thanks Ravi,

– Add Friend/Private Message buttons are hidden on profile page using “BP Registration Options” plugin, for new members only, once ‘approved’ those buttons become visible to the user.

– Add Friend button is hidden on members page (for all users) using code snippet:

 /**
 * Hide "Add Friend" button on members list & search results list
 */
add_filter( 'bp_get_add_friend_button', function ( $button ) {

	if ( bp_is_members_directory() ) {
		$button = array();
	}

	return $button;
} ); 

– So I need the similar functionality as the snippet above; simply hide the Add Friend buttons in the Friends list (for all users), but the friends feature is not disabled.

Thanks!
