Unlock Android with Pattern Lock Without Losing Data

I have HTC One M7 which I wasn't using from 2018. So I forgot pattern lock but I want check data on this smartphone. It's good scope to develop and practice with Android. What I've learn till now: - USB debugging is turn off (after use "adb devices" command phone didn't show up) - I can't unlock bootloader because I will lose data (I don't want it) So, there is any possible way to unlock HTC with forgotten pattern lock and without losing data? Thanks for every help!
