Pixel 6a shows up as Huawei Nexus P6

[peixotorms]

As some users have written on XDA https://forum.xda-developers.com/t/raven-detected-as-huawei-nexus-6p-by-google-device-manager.4498081/ and also experience by me now, I have previously used this pach with magisk, but after a while I removed the patch and unrooted.

I installed QPR2 and after that I also went "back to public" via google website, with a full reset and locked bootloader.

Right now however, Google recognizes my device as Huawei Nexus P6.
How do I reset the fingerprint? Do I have to root again?

Please provide detailed instructions.
My Pixel 6a is Japan's version.

Thanks

Edit:

shell getprop ro.vendor.build.fingerprint

so not sure if it's something else?
