Hardware wallets supports bsc tokens as well, I helped a friend to set it up using Ledger Live for Ledger hardware wallet, you will need to open ledger live on your PC and connect your hardware wallet through USB. Ledger Live will allow you to manage the crypto coins on your cold storage device over different blockchains, the process is just like adding smart chain to metamask wallet, full guide I used for my friend is below.

Importation of your metamask recovery seed into hardware wallet makes no sense, you have simply defeated the whole purpose of using a hardware wallet in the first place, why would you want to generate seed on metamask and import to hardware wallet?.
