PS1, Line 9: 	select FIXED_BOOTBLOCK_SIZE if INTEL_CBNT_SUPPORT

I would rather to have INTEL_CBNT_SUPPORT to be explicitly selected instead of implicit. On the other hand, is there any downside if FIXED_BOOTBLOCK_SIZE is selected for even CBnT in-capable image, such as the image for Deltalake EVT server?
