opt/vc/lib is the very old firmware based 3D driver. Those aren't even applicable to BCM2711/Pi4/CM4.
As linked in that blog post, the 3D drivers are now part of the Mesa library, as they are for almost all Linux systems.
Whether the version of Mesa shipping with Buster is recent enough is anyone's guess.
Raspberry Pi no longer update the Buster repos (and haven't for probably 2 years), and Debian end LTS on it in June 2024, so you are STRONGLY recommended to look at updating.
