Eject internal SSD without manual unplugging

Question

I am experimenting with a boot setup for an external drive. Most of the time, the operation ends up including OSes from my SSD (which I don't want) or messing the boot configuration of my internal SSD, which is an extra work.

To be extra safe, I just want to eject my internal SSD to prevent this from happening again. Disassembling my laptop to unplug my internal SSD manually is a lot of work.

Is there any way to eject my internal SSD in Ubuntu? I mean commands that would do "Safely Remove Hardware" kind of eject, not just unmounting them.

I have tried using eject, udisksctl, udisks, hdparm but it seems that none of these works for internal SSD, and /sys/block/nvme0n1/device/delete doesn't even exist

My internal SSD device path is /dev/nvme0n1

EDIT 1:

I am using Ubuntu Live CD to do this.

Another use case might be:

Doing things (even stupid ones) on a live CD and have great confidence that anything you do there (including installing GRUB for another device) wont affect the internal SSD of the device you're using.

You may overestimate the difficulty to unplug the internal drive. It is very different between computers, how tricky (and time-consuming) it is, but it is worth trying, if you cannot find a way to disable it via the computer's UEFI/BIOS menus. — sudodus, Sep 20 '20 at 13:39
@sudodus I know its not that difficult, I have done it several times. But it isn't what I want to do every time bcs I need tools and time for it. — wthe22, Sep 20 '20 at 13:54
An alternative might be to get a old computer for development and testing (not too old, it should be able to run current versions of Ubuntu, so at least with a Core2Duo processor or equivalent and at least 2 GB of RAM, 4 GB of RAM is much better. — sudodus, Sep 20 '20 at 14:01
Does this answer your question? Installing Ubuntu in a external hard drive and NOT placing GRUB of my C: hard drive — user68186, Sep 20 '20 at 14:03
@user68186 thank you, this is helpful for me even if it doesn't exactly answer the question :) — wthe22, Sep 20 '20 at 14:19
