You will need to remove it from the clock binding and of course from the clock 
drivers. One example is this one:
https://patchwork.kernel.org/project/linux-mediatek/patch/20210914021633.26377-21-chun-jie.chen@mediatek.com/

In the end the mmsys will probe by the compatible and will then probe the clock 
driver as a platform driver.

Best regards,
Matthias
