The short answer is 'no'.

Relative URLs become absolute URLs.  The relative form is merely a short hand
form of an absolute URL.

The scan rules only 'see' the absolute URLs, including the once relative URLs
that have been expanded.

At the risk of confusing you, incomplete 'URLs' in the scan rules are not
relative URLs.  They are partial patterns matched against all (absolute)
URLs.
