Open OS tab and select 'Customized startup' from Boot options.
Add the boot parameters at the end of the 'Command line' and 'Save' the image.
Boot your image on your erasure station (e.g., via a previously prepared USB stick), then manually select the boot option - "Installer" (this is the option that will install Blancco Drive Eraser on the station) and follow the installation steps.
After the installation, remove the booting media (e.g., your USB stick).
On the next reboots, your default booting option will be "Customized startup" and the added booting parameters that enable NVMe hotplug will be passed consistently to the kernel.
