How to de google or create a more private experience with pixel 8

So recently bought the Pixel 8 with my previous carrier being Verizon and was going to put Grapheneos on it but I had no idea that Verizon locks the boot loaders of their devices even though google does not. What are some things I can do to de google the device or make it more private like Grapheneos would. Or am I out of luck....
