Go to BIOS first, then search for Boot Priority Option. Click each of then and disable desired drive.
That just stops them booting.. I assume you want to disable them so when installing one OS it doesnt see the other drives and partitions and attempt to put files in their EFI partitions????
To do that you'd need to disable SATA controllers so the drives are not seen, not just remove them from the boot list
