H1B renewal stamping dropbox 48 months

my last stamped visa on passport expired on January 2019. I am currently in US.

Now I am trying for an appointment in 2023 june. 48months waiver eligibility will be over by then. But when I try to book appointment in cgi portal, and if I answer all questions it lads to dropbox appintment. Please let me know can I go ahead for dropbox. My latest valid visa is still 2025 May.

You can go ahead and book the appointment.
