I don't think any current kernels for the Pixel devices do this but I know they could in the past. Also, it's not as simple as locking ones bootloader for EE users or Verizon users. The warning is necessary but unwelcome as if your bootloader is unlocked you most likely know it is. Either way, Verizon users and European users whom have the need for dePixel8 to have an unlocked bootloader will not be relocking their bootloaders as it's only a matter of time before you will no longer have an unlock method. The root ninja crew said themselves, if you want to have an unlocked bootloader on Verizon and on locked European devices then you need to leave it unlocked. I for one am no gambler and have no desire to close my window of opportunity so my bootloader will remain unlocked as long as I own the device so a mask for the unnecessary warning would be welcome.Never heard of one myself or even the need for it. If one doesn't want a security warning. Then they should lock their device. Pretty straight forward. It would seem like a lot of work for a dev to do for something that is actually working as intended.
