A word of caution. Most of you tech savvy guys won't be this dumb, but I was. I just wasted a few hours I won't get back trying to unlock the bootloader on an "unlocked" Pixel 7 I bought at Best Buy. Turns out carrier unlocked doesn't mean bootloader unlockable. I ordered one today from Google. If I can manage to get graphene up and running, anyone can. Take my word for it. I'll keep you posted.
