You can enable unlocking in the developer menu. That being said I run a stock 8 pro for normie things and use my old 6a to run graphene 🤙

I enabled developer mode but the OEM bootloader unlock seems to be greyed out.. going to probably get an older pixel like the 6 or 7 at some point and try Graphene once I get the hang of Android. Unless you know a way of getting the bootloader to not be greyed out?
