It sounds like the issue is with the lid latch/sensor, not with the graphics. Some laptops may not boot if the lid is closed, and some have options on the firmware to enable to boot when the lid is closed / on a docking station.

From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I don't think this is the problem, as it refuses to boot even when the lid is open
That is why I also mentioned the latch/sensor, it may got stuck.
What do you mean? Like if the lid is open, but it thinks it's closed?
Is it getting stuck in the BIOS? If you can't ssh in, can you even ping it? Network should come up before graphics.
Have you disabled the display manager?
As someone eles mentioned, boot it with a screen and check the BIOS. Since this was a laptop, the BIOS is certainly expecting a display, so you might have to adjust something there.
Yes I can ping it!
Have you disabled the display manager?
yep, I did `systemctl set-default multi-user.target'

I already looked into the bios but it was pretty empty, just a few options, nothing about displays or graphics card
but now I have a doubts, perhaps there is a "show advanced settings" button somewhere that I didn't see? I have to look for it
Most likely it's hard coded in the firmware and not exposed as a BIOS option because the OEM didn't ever think anyone would run into this. The dummy plug is your lowest effort workaround. Hope that works, good luck!
A HDMI Dummy Plug?
These are also good for headless servers. GPUs tend to not "kick-in" if they don't think a monitor is connected.
There's an evangelion joke here that i'm not clever enough to make
Get in the Laptop Shinji.
I didn't think this could actually exist, just ordered one! thanks!
It works great! I use one for a headless server for steam remote play.
Did you take a little journey into the BIOS yet? Is definitely firmware, the question is if you can just change a setting there. Otherwise, somebody already mentioned dummy HDMI plugs.
