The easiest path is just to add a conditional to an override of this template:
buddypress\bp-templates\bp-legacy\buddypress\members\single\profile\edit.php
The name field is, I believe, always:
input type="text" name="field_1" id="field_1"
So in the template, change this:
if ( 'textbox' == bp_get_the_profile_field_type() )
to:
if ( 'textbox' == bp_get_the_profile_field_type() && 'field_1' != bp_get_the_profile_field_input_name() )
and add an ‘else’ to just show the name value – bp_the_profile_field_edit_value()
Great. Where/how can I override that template?
Copy it to your theme or child-theme

Thanks. Although it looks like adding && 'field_1' != bp_get_the_profile_field_input_name() ) has an unexpected effect: with this in place, changing any other editable field and saving it causes the user’s full name to be overwritten by his username slug, i.e. the name “Jonathan Reeve” is overwritten by “jreeve.” I can’t figure out what’s causing this.
I *sort of* got it to work with this hack, although I can’t figure out a way to truly remove the input tag, since it seems to be necessary:
<?php if ( 'textbox' == bp_get_the_profile_field_type() ) : ?>
<?php if ( 'Name' == bp_get_the_profile_field_name() ) : ?> <!-- Don't allow users to edit their names. -->
<label for="<?php bp_the_profile_field_input_name(); ?>"><?php bp_the_profile_field_name(); ?> <?php if ( bp_get_the_profile_field_is_required() ) : ?><?php _e( '(required)', 'buddypress' ); ?><?php endif; ?></label>
<!-- Dummy input, disabled in CSS, because otherwise saving anything causes the user's full name to be overwritten with the username. -->
<input type="text" name="<?php bp_the_profile_field_input_name(); ?>" id="<?php bp_the_profile_field_input_name(); ?>" value="<?php bp_the_profile_field_edit_value(); ?>" <?php if ( bp_get_the_profile_field_is_required() ) : ?>aria-required="true"<?php endif; ?> style="display: none;"/>
<!-- The thing that actually displays. -->
<p id="name"><?php bp_the_profile_field_edit_value();?></p>
<?php else : ?>
<label for="<?php bp_the_profile_field_input_name(); ?>"><?php bp_the_profile_field_name(); ?> <?php if ( bp_get_the_profile_field_is_required() ) : ?><?php _e( '(required)', 'buddypress' ); ?><?php endif; ?></label>
<input type="text" name="<?php bp_the_profile_field_input_name(); ?>" id="<?php bp_the_profile_field_input_name(); ?>" value="<?php bp_the_profile_field_edit_value(); ?>" <?php if ( bp_get_the_profile_field_is_required() ) : ?>aria-required="true"<?php endif; ?>/>
<?php endif; ?>
<?php endif; ?>
Sorry, I forgot to consider the save functions.
Interesting problem.
There are a lot of action / filter hooks in bp-xprofile-classes.
You should be able to add the name field to the $_POST before it starts processing, so that you don’t need an input.
Or overwrite the ‘old’ name into that field value so that the new value isn’t saved, although that’s probably more confusing to the user than just hiding the input via css.
