Hello niskumal,

these roads aren't service roads but tracks.
Please don't do automated edits that change all highway=road to highway=service (see (1)). (Undiscussed automated edits are not appreciated in OSM)

Although the road classification of course isn't ideal as it describes an unknown classification it is way worse to have data with a wrong classification.

Best regards
