iphone 8 got locked, multiple wrong attempts, I DONT want to lose data

Sorry, no they don't. Once the phone is locked, your data is gone.

The only way back in is to reset your phone which will wipe out all the data.

If the phone has gone into security lockout, any data that exists only on the phone itself is gone – or as good as gone. You tell us that you have no backups. That's bad. Backups must be made before a catastrophe strikes – afterwards generally is too late.

There is one more thing you might want to check. If the phone was set up to synchronize data to iCloud – e.g., it was set up to use iCloud Photos – synchronized data that had made it to iCloud would survive the erasure of the phone, and could be restored by re-synchronizing the phone (or another device) to iCloud.

You could check if there is anything in iCloud by logging into https://www.icloud.com/ from just about any modern Web browser – on a Mac, Windows PC, Linux PC, or even a ChromeBook.

Note that if you were not using iCloud synchronization on the phone, it is too late to save any data by turning it on now. You must turn on synchronization on the phone itself – and you won't have another chance to play with the settings until after you erase the phone to get back in.

Passcodes and passwords - Apple Support

"If the Erase Data option is turned on for iPhone, iPad, or Apple Vision Pro (in Settings > [Optic ID], [Face ID], or [Touch ID] & Passcode), after 10 consecutive incorrect attempts to enter the passcode, all content and settings are removed from storage. Consecutive attempts of the same incorrect passcode don’t count toward the limit."
