RMAN-06172 while trying to restore controlfile from old backup (in tape)

I am trying to restore controlfile from very old backup in tape to a new server.

DB is now in no mount mode and my restore controlfile command failed (Although backup team confirm controlfile backup piece is available and showing in their console).

RMAN-00571: ===========================================================

RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============

RMAN-00571: ===========================================================

RMAN-03002: failure of restore command at 11/17/2020 18:15:18

RMAN-06172: no AUTOBACKUP found or specified handle is not a valid copy or piece

I cant change config statement as the DB is not mounted.

configure CONTROLFILE AUTOBACKUP ON;

Please suggest
