I can unlock my phone by fingerprint but I had forgotten my pattern and I cannot change my pattern it is any option to change it that does not involve reset.

If you can unlock the phone by fingerprint, you can change the lock screen to None. then start the fingerprint-pattern setup again. (And draw it out and stick it it in a drawer somewhere.)

If the phone was off, you need the pattern first, to use the fingerprint, so see if your carrier can help you.
