An option is to compile the keyboard firmware from source code. See, e.g., this for details (just the setup and compile part): How to add different RGB colors to specific layers on the Keychron K0 Max [Tutorial]. For a K0 Max.

It causes problem for some KVMs as well. An example would be K0 Max. It isn't cheap, either. References K0 Max default ke

Re "the Keychron K0 Max isn't available as a keyboard through QMK": The source code is in a fork, not in the main QMK project. And not in the default branch. The setup part (after the prerequisites) can be done in a single step, using a few parameters for 'qmk setup' (Git and/or Make gyrations are c
