When installing graphene os I would consider very carefully if you want to relock the bootloader. In the past I have installed graphene os on my pixel 7a and a normal system update broke my system and made it unbootable. Because of the locked bootloader you can't reflash the os without wiping your data. It may be a very uncommon bug that may never happen to you, but honestly it shouldn't have happened to me either.

Ive been using GrapheneOS for years and was in the chat rooms a fair bit, this isnt something common. Sounds like it may be hardware failing.

Having bootloader locked you get verified boot, big security benefits and automatic healing of operating system files damaged by the drive degrading.
