Hyperpixel 4 drivers in Bullseye and OpenGL ES

Do the drivers that come with Bullseye support direct GPU rendering with the VideoCore IV based Pis? Are they DRM/KMS drivers? I use Pi OS Lite without a window server, and do GLES based on the ubiquitous “kmscube” sample code. Thanks! (By “direct GPU rendering” I mean without fb to fb copying which is done by some spi TFT drivers).
