I found some documentation about Kext, but I heard they have now moved to Dext. So I was wondering if Dext could completely imitate the previous Kext.

This page is written like this
Important In macOS 11 and later, the kernel doesn’t load a kext if an equivalent DriverKit solution exists. You may continue to use kexts in macOS 10.15 and earlier.
