If I got it right what is meant here is the ability of device  to generate the child seed from master SEED extended by passphrase, If this correct then  Passport batch 2  also supports BIP-85 Passwords ^{being the owner of this device I say this for certain}. I utilize this feature to generate ^{on passport 2} child SEED for my Tangem 2 which is  used by me for on-the-go activity.
