[Q] Deactivate recovery mode and adb

Hi,

I'd like to build a custom kernel which has full control over the installed ROM's and Kernel's by an own certificate routine. Is it possible to build a kernel with a bootloader, which deactivates the devices recovery bootloader like the original Samsung custom OS loader Odin mode (vol. down + menu + power)? Is it also possible to lock a device to avoid a connection by adb. I assume the bootloader is not part of the kernel and can't be overwritten, but is there any way?

Regards,
