You cannot mark a whole drive as bootable. You can mark a primary partition

A compliant BIOS does not require a bootable partition.
Ah, OK, I hadn't realised that (that marking bootable isn't
necessary).
IF the BIOS is compliant.
How does the BIOS decide what disk to boot from then,
does it search for the MBR signature?
Yes, but any disk with a DOS or GPT partition table has the MBR
signature, and not all MBR contain a boot code. Usually, the boot
preference order is defined in the BIOS setup.
Update fstab and the initramfs.
OK, fstab is easy enough. Do I just run update-initramfs for the
initramfs?
Yes, if the initramfs generator is initramfs-tools, with -u (update).
With default options (MODULES=most in /etc/initramfs-tools/), the
existing initramfs should already include NVMe support.
