Can I substitute something else in using finger print on my MacBook Pro?

I have no idea what you are asking... the alternative is type in your password.

You can delete a problem finger print if not working, and you can add or re-add finger prints.

ref: Add or delete fingerprints on your Mac

ref: Use Touch ID on Mac

ref: If Touch ID isn't working on your Mac - Apple Support

There are a few instances where Touch ID will not be accepted by macOS:

• If you restarted your Mac, or if you're not logged into your user account.

• If you have not unlocked your Mac for 48 hours.

• If you are trying to unlock Security & Privacy

• If you are trying to unlock Users & Groups Settings (when FileVault is on)

• If 5 wrong fingerprint attempts

If you mean another body part, the answer is no.
