The rtw88 driver in the upstream kernel is under active development and has been adding support for 8822* chips, but I'm not sure what state things are in with the 5.10 kernel used in LE10, it might need something a bit newer to have things work.
DKMS solves a different problem. It allows you to recompile the driver to match the kernel - but it assumes the driver can be compiled for the kernel in the first place. LE's problem is that we frequently bump to the latest kernel and this results in drivers that simply do not compile on the target kernel version. Over time (and multiple drivers) you get rather bored of reinventing this wheel.
