OEM Unlock grayed out on a GB7N6 Pixel 6

today I exchanged my Xs Max with a Pixel 6 and when i got home i saw that it is A15 Beta and through what i saw when checked the internet A15 in pixel 6 is hell and breaks pixel 6s so I wanted to roll it back to A14 but OEM Unlock is grayed out and says to connect to internet or call carrier

I checked this form from XDA and this thread in reddit that says the phones model which i found in this website is unlocked and now i dont know what to do from here. should i return it or is there are more stuff that i dont know and havent found out yet
