Question Tried everything but Laptop can't display to HDMI after disabling integrated graphics

Dec 6, 2019
Hello All,
I have an Acer Aspire E5 573 laptop and the screen is smashed, hence why I use an HDMI cable to plug it into a separate monitor and it worked just fine. However, yesterday, I did something really dumb and I disabled the Integrated Graphics from Device Manager and it is no longer displaying to my second monitor.

I've removed the back panel of the laptop and removed the CMOS Battery and took it out, waited for 3-4 minutes and to no avail, I still don't get an output on the monitor.

Finally, please keep in mind that my laptop primary display is smashed. So I can't see what's going on there as well. All I know is that the Computer is Working, as when I press the Windows key, the smashed screen kinda changes colour.

Is there anything I can do to resolve this issue?

The laptop has an Nvidia GPU in it, but I can't change it because as I mentioned before. I have no display.
