My laptop screen flickers when on battery power

My computer screen is flickering anytime it isn't plugged into AC power. I have figured out that this is an issue with my drivers and that I need to update them. But when I got to the Intel graphics drivers page there was no option to download drivers for Linux/Ubuntu. Is there is any way to update my Intel graphics drivers on Ubuntu?

I'm running Ubuntu 20.04 LTS on a Lenovo IdeaPad 2-in-1 4GB with an Intel Pentium 4415U.

The flickering looks like this: https://www.youtube.com/watch?v=5Vl3EmyZX2s

There is no need to upgrade your drivers. In older Ubuntu versions, the graphics driver was distributed as xserver-xorg-video-intel, which is updated as part of the system by Software Update. Since 21.04, the default Ubuntu session uses Wayland, which in turn uses DRI/DRM. Now, drivers are an integral part of the Linux kernel. Instead, you need to verify that the problem is exhibited in another operating system, or in the system firmware, to distinguish it from a hardware issue.
