Depends. Some tokens can never be fully reset (e.g. TeleSec NetKey). Others 
can be reset for example with gpg --card-edit's factory-reset command (which 
may or may not be present in gpg 2.2.20) or with the (currently unreleased) 
gpg-card's factory-reset command. (gpg-card, the new administration tool for 
smart cards, will be part of GnuPG 2.3.)
