The option is expanded before use, so you can certainly make what it
expands to conditional (the default already is). As for conditions,
"AUTH" is easy. But an AUTH message may be addressed to both local
and offsite recipients, and the received header is added per-message,
not per-recipient. So avoiding "AUTH and local" but not "AUTH and
outbound and local" would be tricky. You'd have to play games with
the RCPT ACL, accepting only local or external recipients (whichever
you encounter first) and defering the rest.

For simple AUTH, a change like this to the beginning of the default
value documented in spec.txt:

received_header_text = Received: \
    ${if !eq {$authenticated_id} {} {from an-authenticated-host\n\t}\
    {${if def:sender_rcvhost {from $sender_rcvhost\n\t}\
    {${if def:sender_ident {from $sender_ident }}\
    ${if def:sender_helo_name {(helo=$sender_helo_name)\n\t}}}}}\
...
