Blocking pattern huawei p20 lite?

I bought a huawei p20 lite on ebay where the display was broken. Now the display is completely back, but unfortunately I can't use it because the previous owner has created a locking pattern and I can't reach it to solve the problem. My question here would be, can you somehow solve the locking pattern differently? Mfg Enno

To reset it (all personal data will be deleted!), You have to shut down your mobile phone first.

Then you hold down the power button and the volume down button. If it doesn't work the first time, just switch it off and try again.

Then you come into recovery mode (navigation is now only possible with the volume rocker and power button!). You move with Volume down to the point "swipe data factory". Then you confirm with the power button. Then you go down to "yes" and confirm that. Then it loads briefly.

Then go to "reboot system now". Your cell phone will now be restarted and you will have to set it up again.

Yes, I thought so too, but unfortunately it no longer works with Huawei p20 lite. Since the boot function was blocked by Huawei.
