'scrolloff' is a global option, :setlocal can be used to change a global
value (and does not complain):
:h 'so

There are
* global options (one value is shared by all buffers, example:
'scrolloff'),
* buffer-local options (each buffer has its own copy, example:
'readonly') and
* global-local options (buffers *can* have a local copy; if not, the
global value is used; example: 'autoread').

:h local-options
:h global-local

You could try to change the global option 'so' on each BufEnter event.
