Yes that's possible.
In global.php add:

eval("\$header_nobuts = \"".gettemplate('header_nobuts')."\";");

right after this:

eval("\$header .= \"".gettemplate('header')."\";");

Then create a new template called header_nobuts, and use $header_nobuts where you don't want buttons.

Oh and add header_nobuts to the end of the list here:

$templatesused.=',pagenav,pagenav_curpage,pagenav_firstlink,pagenav_lastlink,pagenav_nextlink,pagenav_pagelink,pagenav_prevlink';
