Unlocking iPhone without knowing security code

My mom has advanced late stages dementia and she is no longer capable of remembering her security code to her phone. I’ve tried all the usual suspects but am unable to make any progress.

Is there a way to retrieve her information, pictures, voice mails, etc. without doing a hard reset? In other words, I know things are backed up to the iCloud but is there an actual way to get that data that is stored in her cloud if I have to reset the phone?
