If not, is there a way not to mount it ?
If you don't use it, it's not useful. :) Disable it in your kernel and it will go away. debugfs is not a real filesystem, it's a virtual way to access debugging info from various modules/programs. Kind of like /proc is a virtual filesystem which shows info about processes. If you don't use any of that debugging info, then it's useless to you.
