is there an option to get my phone unlocked without erasing my phone

Unfortunately, no. If it gives you a waiting period before you can try again, wait it out, then try your passcode again.

If the phone is unavailable, you will have to reset it. If you made backups, you can restore your data from them.

If you forgot the passcode on your iPhone, or your iPhone is disabled or unavailable -

If you see an iPhone or iPad unavailable message or Security Lockout screen - Apple Support

If you forgot your iPhone passcode - Apple Support

EXACTLY one option:

Correctly enter the passcode after the “time out” expires.
