What is CSM boot mode?
CSM is something that allows booting in legacy BIOS mode on UEFI systems.

Legacy + UEFI boot mode can take care of the two boot modes.
Can a GPU run on a UEFI BIOS?
It goes a little deeper than that but for a quick answer yeah, this. Essentially CSM allows devices designed to run on a BIOS system to still work with a UEFI system.

Can a Windows 7 computer boot in UEFI?
As you’ve noticed, the Compatibility Support Module can be required by the operating system for UEFI boot, not just legacy boot. This is the case for Windows 7. There are in fact name-brand computers that even lack a CSM and cannot boot Windows 7 at all.
