There is no direct method for doing this, as SharePoint doesn't support
column-level security. What you can do is play some tricks with lookup

"lookup" lists.

Here's what I'd do, and keep in mind that I'm not a developer.

Edit the editform.aspx page, so that it doesn't contain the field that
you don't want to be changed. Unfortunately, if users have the ability
to create their own views, they could create a view that contains the
field, and "Edit in Datasheet".

If you turn on content approval on your list, though, they won't be
able to actually change anything when they switch to Datasheet mode.
