They're not necessarily service roads --- they don't have to lead to
any premises at all; they're simply minor roads, usually unsealed.
Then maybe:
highway=unclassified + unclassified=byway + surface=unpaved?
Or highway=road + road=byway + surface=unpaved.
Some (but very few) "BOAT"s near me say "service road" to you when you
look at them; most just say "track" or even "bridleway". The only
"unclassified" ones I can find are as a result of some newbie's* mapping
and probably could benefit from a resurvey to see if they're best
described as service roads or something else. I certainly wouldn't use
highway=road if I'd been and had a look, as that implies that no survey
has taken place.
Essentially - map the physical and legal attributes separately; but map
both as accurately as you can.

* me, back in 2009. The overpass query for info was:
<osm-script output="json" timeout="25">
<!-- gather results -->
<query type="way">
<has-kv k="highway" v="unclassified"/>
<has-kv k="designation" v="byway_open_to_all_traffic"/>
<bbox-query {{bbox}}/>
</query>
<!-- print results -->
<print mode="body"/>
<recurse type="down"/>
<print mode="skeleton" order="quadtile"/>
</osm-script>
